Benjamin Stowe's Review Sourced from Google
Read the reviews people, while most of the time, calls are okay, customer service is impossible. They assign you a rep with a name that you can not pronounce and they don't have a phone number! You have to email in hopes that they might respond. We were sent a new phone "equipment" and it didn't come with a power cord. They tried to tell me that is normal. Brand new that isn't normal. They said it gets power from the ethernet cord. So, I tried that, nothing. Been waiting 2 month for the return to be processed, nothing. Box is still sitting on my desk.

This company is AWFUL! DO NOT USE THEM!Customer service sucks. They made a mistake when trying to change licenses and they have been overcharging us for months due to their mistake. They have hidden fees that they have NOT ever made anyone aware of. Not listed in the statements anywhere, and not listed in any contract. They will leave you waiting for weeks, months even before getting back with you or trying to fix your issues. They will send all their other reps to try to upgrade our services but not actually address the issues we have.

David Shempert's Review Sourced from Google
8x8 continues to attempt to charge us $838.16 as a cancellation fee. This cancellation fee should not be charged. We attempted to work with 8x8 to resolve long standing service issues regarding dropped calls, missed calls, call quality and general call technical issues. 8x8 made NO attempt to resolve the issues at hand and we even brought in a technical expert to ensure that our network was not the issue. 8x8 made several contractual breaches throughout the service term. We also never signed a specific contract stating a specific service term. The business claims we signed electronically but we were never told clearly that would be responsible for fees for services that we are not receiving. 8x8 is definitely a scam with regards to charging customers for money and not ensuring that they have the proper working services to support the charges. We would like to have all charges waived at the least and consider a pro-rated refund for service charges which we previously indicated we had continuous call quality issues. It's egregious that your company believes that they can just overcharge customers and not make any contact with them until we show up to cancel your scam service. We would appreciate corporate insight and assistance in this matter as we will take any and all measures necessary to protect our assets and ensure that funds are allocated as delivered. Which in this case the services that 8x8 was contracted to provide they contractually breached by failing to properly deliver phone services at the quality described when we originally signed up for the service. We intend to present any and all findings of fact in our proceedings. Please respond as soon as possible to this complaint before further action is taken as needed.I cannot believe that I actually recommended your service at one point.

Gigaleads truly impressed me. From the initial contact to the final results, everything was well-organized and highly professional.What stood out most: they think along with you, act fast, and stick to their promises. No empty words, just leads that actually convert. My calendar is filling up with high-quality appointments. For entrepreneurs who want real growth without the noise, this is the team to work with.

One of the best 💯 I would say I will always choose to be with this friendly, fantastic and very accommodating company. I always had a chance to to be hired with other bigger companies but I'd rather choose BIGOUTSOURCE no matter what. It's actually my second home. I feel safe and happy when I'm with BIGOUTSOURCE. I love everything about it. ❤️❤️ No doubt this company is one of the growing company in the Philippines. ❤️

Holly has been a great help recently both in terms of my business and personal affairs. I am in the process of making some business structure changes in my private dental practice and she has assisted me with all the lengthy paperwork, ensuring that everything is in order. In addition, she has assisted me in researching properties and locations. I would not hesitate in recommending her services as her support has been invaluable to me at this extremely busy time and has allowed me to focus on my patients.Highly recommended +++++

Terri has been an incredible SmartPA assistant for our family over the past 18 months. Her support has been invaluable in managing our busy work and home administrative tasks. Throughout our travels across Europe, the US, and Canada, as well as during our recent move to a new house and country, Terri has been there for us every step of the way. In particular, I have appreciated that Terri has used great judgment in assessing options on all fronts and hasn't just gone for the easy road of blindly following orders. I have trusted her as a "second me" and that has been so helpful. We couldn't have done any of this without her!

I've been working here for over a year now as a Junior Executive - HR, and it's been a great learning experience.I've always felt that if you're willing to learn and put in the effort, you're given the chance to grow and take on more responsibilities. The recognition culture here is something I really appreciate as well. Whether it's Employee of the Month, Team of the Month, Pinnacle, Maestro, or other achievements, it motivates employees and makes us feel that our hard work is noticed and valued.I'm especially grateful to my manager for the guidance and support throughout my journey and to our director for the trust and confidence he places in employees.The work environment is supportive, and everyone is encouraged to learn and grow. It's also the small things that make the workplace special,even birthdays are celebrated, and those little moments bring everyone together and make people feel appreciated.All in all, I'm happy to be part of the team and grateful for everything I've learned here.
