Featured Client Reviews
"We've been with Expo-E since 2017 and their service is very reliable. Previously we were with Virocom and their service was utterly diabolical and unprofessional. We have had some brief outages with Exponential-E since 2017 but the important thing is outages are immediately acknowledged, triaged and remediated as quickly as possible. Which is more than I can say for Virocom. There's nothing worse than experiencing an outage and having no one available to help or no information available. That's why we moved from Virocom to Expo-E. Exponential-E has a wide portfolio of services and experts who can deliver solutions within the tech lifecycle. Prices are competitive too. I highly recommend them."
"Their treatment of us as a longstanding customer has been outrageous; we have been paying £600pm where, I now find out, the going rate is less than half. They have moved us to a new contract which means we are “only” overpaying by jaunt under £3,000 over 3 years. I would avoid them like the plague."
"Poor account management and sales advice before during and after project deployment. Existing customer. Will not deal with these individuals going forward. Great tech and knowledge let down by the rest."
"I was a long term customer who needed an internal shift, the customer service and provisioning team have really let me down. Used to be a good company but something has gong badly wrong. Avoid!"
"Don't usually write reviews but after 8 years of being with Exponential E must say the premium in costs over their competitors is worth it. Service great as always. Thank you"
