We were in contract with Toople for many years. Since 2019. In fact we had 3 contracts running in parallel. Our last of the three annual contract did switch post Covid to a monthly rolling contract. We did the past month provide Northern Telecom with the necessary notice to switch to another more competitive provider. Once we had paid the monthly invoices and the termination date had passed we received a further invoice from them with a 25 pound charge and a call charge for 14 p. The narrative reads Additional charge.When I enquired what is all this. They said that somewhere on their T&Cs they say that they will charge a 25 pound admin charge at the end of a fully paid conract. I protested that this was never mentioned in all our communications whereby only the termination notice and the rate per month was discussed. I also mentioned to them that these charges were never applicable in any of the other two contracts that were all agreed at the same time. Believe me when I say these people are dishonest the tell you they would charge you 26 pounds for example but in effect for a short year contract they actually charge you through this admin charge 2 pounds more per month. AVOID is my suggestion , avoid because they hide their true monthly charges and by doung so they stop customers from using other TRANSPARENT alternatives. NEVER AGAIN.
