Cancellation Of Service that MWeb will not accept

We are a long standing customer with MWeb and the offer was an upgrade in June 2015 which we agreed too, after 90days we cancelled it and decided to look elsewhere, now MWeb will not accept the cancellation even though they cannot confirm an installation date. MWeb claims that Neotel will not let us out of the upgrade and they have a back to back arrangement with Neotel. MWeb also want to claim 75% of the 2year contract in a form a penalty. Neotel have said that both of the claims made by MWeb are FALSE. We have taken the matter up with the Telecoms Relationship Controller, Shivonne Fortuin and all she can tell us is that MWeb is waiting for an installation date. MWEb is a business and not a humanitarian organisation. They need to make a profit, they have yet to learn that the best way to improve your bottom line is to LOOK AFTER YOUR CUSTOMERS. We are not going to accept MWeb's position in this matter. We will fight them on the beaches, We will fight them in the boardroom, We will fight them in the canteen. WE WILL PREVAIL!!!
