Call Centers Review from Eric Jones
Answer365 was the answer to our problems. We receive an insane amount of calls to our venue and Answer 365 was able to step in and save the day. Extremely professional and Agile, I would completely recommend this firm if you need some help with your call volume.

Call Centers Review from Paul Tennen
We have been using the services of Answering 365 for years now and we could not be happier. They have a friendly staff, are always attentive to our needs, and are very pleasant to speak to on the phone. We use them for our after hours call needs. They have always been reliable and friendly to the residents and clients that we service. We are very grateful for the help of the staff at Answering 365.

Call Centers Review from Amy Hendel
We have been using this service when it actually had another name - so for quite some time. Overall we are quite pleased. only issue is occasionally when we hand off coverage for the weekend - when the doctor is off call - all the operators somehow do not “get the message.” I do endorse them as a good service, their billing department is responsive - they just need a bit of a tweak in the training of their telephone operators with this “hnd off on weekends.” I would recommend them as reliable and responsive.

Lead Generation Review from Josh Kaye
Complete Scam.Hired them for lead generation.Delivered bogus made up leads.Beat us for 10,000$.Zero return.Avoid at all costs.

Email Marketing Review from Josh Kaye
I recently engaged Cience Lead Generation, paying $10,000 for 250 qualified leads, expecting a professional service and solid prospects. Unfortunately, what I received was far from that. The leads they presented were completely fabricatednone of the individuals or businesses had requested information about my company. In fact, we obtained sworn affidavits from many of these so-called "leads" affirming they had never heard of us or requested any information.This is a blatant scam, and we're now in the process of pursuing legal action against Cience to recover our full payment. If you are considering working with them for lead generation, I strongly urge you to reconsider. Their practices are fraudulent, and you risk losing a significant amount of money without getting anything of value in return. We were misled, and now we're facing the consequences of trusting this company. Dont make the same mistake.

Call Centers Review from Anonymous
Please extend our sincere thanks to the team for all they are doing on behalf of our patients, providers, and partners. Their efforts have given welcome bandwidth our clinic staff to focus on the people in front of them and on better health outcomes. Even from my start in June I have seen (and been told) the great improvement in the quality of our patient interactions and clinic communications. I have been so encouraged by the team's willingness to do the right thing, to constantly coach and improve, adapt to change, and treat the patients with empathy and respect. Thank you. I am looking forward to what next year brings as we bring on our remaining clinics, launch new or improved campaigns, and continue to build a foundation for success, growth, and patient care that sets a new benchmark!

Most businesses I work with are hesitant to hire a call center for their company for multiple reasons. However, the AlertCommunications team has been the best company I’ve worked with in over 5 years. Especially, Jenilee Ramos. Anytime I need insight on a call, she is reliable!! The AC team has always been attentive, responsive and pretty awesome at what they do. I highly recommend using this group for your company’s needs!
