theft by telkom

I had a complaint a whole ago about telkom giving me the wrong internet, I had it sorted out but they billed me for an additional month. I have returned the modem, had the contract cancelled and was assured that I dont owe anything anymore. Today money was deposited into my account and immediately R 1000 was deducted by Telkom even though I stopped the call order at the bank. I will be making a case of theft at the SAPSS TODAY. I am a person living on the breadline and cannot afford a huge multimillion rand company *****ing my money. DONT EVER SUPPORT TELKOM MOBILE.
