Failing to contact your client, telkom regarding handing over client incorrectly

Hi! I have been incorrectly handed over. My line was cancelled in May and I was charged twice for the same thing. I have since been in to a telkom branch and been told what to pay and have been shown that my account is paid up and cancelled! I am being harassed by MBD and it's not correct!!! I do not owe you any money. I have written communication from an agent at telkom saying my account is paid up and even with this MBD will not withdraw as telkom handed over a different amount. It's insanene. I have a million reference numbers to give you regarding this. Please assist me to sort this out asap! I have emailed Boitumelo and she refuses to acknowledge or contact telkom regarding the fact that the error is from the telkom side and not mine!!! I've had enough. It's absolute harassment!
