Customer Support Review from Manoj Thenua
I recently engaged a customer support provider to manage client service and support tasks for my healthcare-oriented platform. From the outset, their team was extremely professional, responsive and attentive. Their onboarding process was smooth, prompt, and well-organized. Throughout the project they handled all support tickets including account queries, billing questions, technical issues and general user guidance with empathy and clarity.What impressed me most was their commitment to quality: they consistently responded quickly to inquiries (often within minutes), maintained a helpful and courteous tone, and followed up until the users problems were fully resolved. Feedback from my users has been overwhelmingly positive: many praised how easy it was to get help and how satisfied they were with the assistance.Thanks to their efficient support, user satisfaction and retention improved noticeably compared to the period before they handled support. I also experienced fewer escalations and received fewer complaints overall. Their professionalism and consistency gave me peace of mind and freed me to focus on growing the platform rather than handling day-to-day support issues.Overall, working with them has been a very positive and productive experience the quality of support exceeded my expectations.

Phone Answering Services Review from Anonymous
Top quality service and customer care, really impressed with Face for Business and I couldn't recommend them any higher!

Phone Answering Services Review from Nora
We have been using Face for Business services for a few years for our financial advice company. We can not fault their service, it has proved extremely useful, especially post-Covid in particular when we all moved to working from home rather than being in an office.

Phone Answering Services Review from Joshie
I took over a busy clinic a few months back and on the days there is nobody to answer the phone these guys are ready to step in and intercept the calls ensuring no business is lost. I am very thankful for this great service and I highly recommend Face For Business as a professional and friendly team!

Porting my phone number over to Answer First was ver easy and simple. Allison was quick to find answers to my concerns and walked me through the process efficiently. I am really happy with my experience.
Justine Karren's Review Sourced from Google
Recently signed up with AnswerFirst and couldn't be happier! We've also received nothing but positive feedback from our clients. We also contacted support for the first time and our request was completed within a half-an-hour of creating the ticket.
Karen Mason's Review Sourced from Google
Extremely disappointed. After assuring me that they could pre-qualify callers, they decided that they really couldn't do that and re-wrote the scripts in such a way that I might as well use AI or even a simple voice activated call routing system. They declined even the simplest request: I wanted them to add callbacks to the first available time slot on my schedule -- NOT to schedule the callback time with the client, just to put the message on MY calendar so I would have time carved out to return the call. For some reason that was too hard for them. They did, however, send me messages that were supposedly for me, even though I had never forwarded my lines to them.The response below says they couldn't schedule a callback without the callers permission, which only proves my point that they didn't listen so they didn't get it: all I wanted them to do was add the message to call back to my calendar rather than just taking a message. How is that doing anything without the caller's consent? It was just meant to block time in MY day. Nothing more.If you couldn't qualify callers in your environment, you should have said so when I asked.

Five stars for the amazing culture! Working at KamelBPO has been a great experience. It’s a fun environment where you feel motivated every day, and the management truly supports your growth. Highly recommend!
Rolando Jacinto (Pinkish)'s Review Sourced from Google
As an independent contractor at Kamel Media, I can say that this company is truly amazing and promotes a great work-life balance. I would definitely recommend it to my friends who feel exhausted in companies that only prioritize numbers rather than their employees.I worked in the BPO industry for quite some time, and I used to feel very tired and burned out. That changed when I discovered Kamel Media. The environment here is supportive, and the team genuinely cares about the people they work with.The support has been excellent, and I am very grateful. Thank you, Kurt and Mariannah! 😊

5 Frequently Asked Questions About Telemarketing Firms
What do telemarketing companies do?
Telemarketing agencies use phone-based direct marketing to sell products, generate leads, or book appointments on behalf of businesses, performing both outbound and inbound calls to grow sales pipelines and client relationships.
As all telemarketing interactions involve direct human contact, the approach allows them to influence potential customers’ opinions, purchasing habits, or perceptions toward a brand.
What services do telemarketing firms provide?
Telemarketing services for businesses can be split into two main categories: inbound and outbound.
- Inbound telemarketing services cover customer support calls, namely technical support, order taking, billing inquiries, upselling, and virtual receptionist service, to name a few. They can support both B2B and B2C companies.
- Outbound telemarketing services, also referred to as proactive outreach, are intended to boost businesses’ bottom line. This category comprises several different service types, including lead qualification, appointment setting, cold calling, customer reactivation, and more.
B2B telemarketing companies are often hired to assist non-profit organizations in soliciting donations or to collect debt and follow up on overdue accounts on behalf of other businesses.
How much do telemarketing agencies charge for their services?
Telemarketing agencies charge between $7 and $75 per hour for their services. The service cost can also vary based on location (offshore vs. onshore), campaign complexity, duration, and agent experience, with B2B telemarketing campaigns often costing more than B2C.
Other common pricing models include:
- Per-lead: $35 to $60 per qualified lead
- Flat-rate: $650+ for a 4-week campaign
- Commission-based: 5% to 20% of each closed sale
How long do telemarketing campaigns take?
Telemarketing campaigns usually take a few months, as lead nurturing takes multiple phone calls for telemarketers to engage with a prospect and close a sale.
Although initial lead generation begins within the first few weeks, for a full, effective cycle, the campaigns are run between 3 and 6 months. The average campaign takes about 14 weeks to reach an optimum level of opportunities per day. The length also depends on the campaign type:
- Pilot and trial campaigns: Usually run for 10 to 12 weeks to test the market, refine the pitch, and validate traction.
- Short campaigns: 4 to 6 weeks for time-sensitive promotions or event registrations.
- Long-term campaigns: 6 months to over a year for slow B2B sales cycles that require more lead nurturing.
What kind of ROI can businesses expect from telemarketing campaigns?
Lucrative telemarketing campaigns often result in a 5:1 to 10:1 return on investment (ROI), meaning $5 to $10 in revenue for every $1 spent. The return rate depends on the quality of the call lists, the persuasion skill of the callers, the product, the offer, and whether it's part of a multi-channel strategy. Notably, ROI grows over time through stronger customer retention and better targeting informed by feedback from calls.
