Billed Incorrectly

Dear Telkom Mobile,<br> <br> I cancelled my contract with you two months ago, queried the incorrect billing statement about 4 times you did not fix this yet you keep debiting my account......Every time i call you promise someone will call me back and I never receive a call, that is lame.<br> <br> Please note, I will be reversing the debit order and porting my number while you think about calling me.<br> <br> Regards,<br> Angry Customer
