unfair customer service

i had 24 months contract with Telkom since the beginning i had unathorized debit coming off my account i took it up with them and it stopped and in November it happened again i then called my bank to stop such debit but to leave the contract i had with Telkom however my bank stopped everything coming from Telkom which result in me getting penalized by Telkom for stopping the debit my subscription was R207 going off 20th of each month i was charged double amount from Dec till Jan without Telkom notifying me of the situation, but still debiting my account month end. So i feel that was an unfair treatment i was supposed to be informed before hand to rectify the situation. than having to be charged this exorbitant fees that could have been avoided. I send request to them asking for those rejection fees reversal but no body came back to me i feel abused by the network provide for even paying exorbitant money while dont even have access to service
