Unauthorised funds removed from my account.

If I have a limit set as maximum R199 per telephone how can you deduct R1100 from my account and then tell me it is for data? I called the call centre and a Trudy refused to give me a reference for my call and promised she would mail her response to me so I had something in writing but never did. When I asked for a senior I get Trudy coming back to the phone, all this in a call that lasted about 50 minutes and ended with no resolution.<br> <br> Trudy tells me I must go into a branch and go and cancel the data. I will not cancel something I did not request or authorise.<br> <br> My contracts ended, Telkom have no right to add data pack costs to my account without my authorisation and they may also not exceed the set cost limit I app****.<br> <br> I want my money back!
