Worst service ever

My account was suspended from the 15th of August 2015, I was told it's a system error but my account is up to date. Noluthando Madela who is a team leader told me that there's nothing she can do (in that managerial position she holds). That was after several other team leaders promised to call me back but they never did, while others cut the call while I was talking to them. <br> Telkom will debit the full months subscription but I only used the line for half a month! <br> I want to cancel this contract with immediate effect as I won't tolerate this kind of service I'm getting from Telkom as a service provider as well as from the representatives of Telkom Mobile which are the agents together with the team leaders. <br>
