      Lead Generation Review from Nathan Arbitman

      I'll be honest, I came in skeptical. Offshore SDR vendors have a reputation for generic blasting and slow response times. Munzai has been the opposite. Responsiveness is where they stand out. When I need a cadence adjusted, copy reworked, or targeting updated, it gets handled quickly, without me having to follow up multiple times. For a solo commercial lead juggling a lot, that matters more than I expected. The value is hard to argue with. For a very fair price, I get dedicated outreach execution across a complex B2B pipeline. They also got up to speed faster than I anticipated. Our market has real nuance, and within a reasonable onboarding window, messaging was going out clean and on-brand.If you're a lean commercial team trying to build outreach capacity without the overhead of a full hire, Munzai is worth a serious look.

      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.
