Telkom ********l debiting customers

Every month I have an issue with Telkom. All I want is to pay my R599pm contract with Telkom but Telkom insist on making ******** transactions on my bank account and Telkom account. On the 04/04/2016 I received an invoice ********ly charging me for termination fees after Telkom agreed on not charging me ANY penalty fees due to being sold the wrong device in the first place(which I have documented proof of). I reported it and got a response from Telkom that someone is dealing with my case, NOBODY contacted me and then on the 15/04/2016 Telkom attempted to debit my bank account for R2000, causing me bank charges for an unsuccessful debit. I do not understand why they attempted to debit my account for R2000 on the 15th as my debit date is the 25th and my contract is R599pm. I called the Telkom support centre and took 20 minutes explaining my case with a consultant who gave me her manager's name as Sifiso Madondo and refused to give me his email address. After taking all of the details she puts me on hold \in order to log the case\". After holding for about 7 minutes the call gets put through to a survey and then cuts the call. In addition to all of this, I have no internet connection."
