Telkom - Bunch of *******

I have instructed telkom to set my spend limit to R10 wen I initially took my contract.The consultant whom I spoke to said me that it's all sorted out from his side.But recently they have being debiting R500 extra from my account for the last two months.After I queried why, I was told that my spend limit was set at R500 . Spoke to numerous consultants but none of them can help . Waiting over a month for manager to call me.I even emailed a manager but no response.I'm requesting for telkom to listen to recordings which they refuse to do.Telkom is a ***** they just be ***** ur money and do nothing to rectify the problem I guess they are doing this because they know my contract is ending.I will never recommend telkom to anyone.
