Withholding important information from customers

On June 17th 2017 I took up a new contract with Telkom, the consultant advised me that the contract will be R579pm for 24months. When I received my statement on 2017/07/04, the total amount due was R1405.20, I immediately contacted the call centre to advise that I am not able to pay that amount and that the consultant who opened the contract made an error, the call centre directed me back to the store where I opened the contract, at the Clearwater store I was told there is no manager appointed, however another consultant will assist me and log a case for me, which will take 40 working hours to be resolved and that was on the 12th of July 2017. Ever since I received my statement on 2017/07/04 I have been following up with Telkom almost every day, the records will show all my calls and you can listen to the recordings and just yesterday the matter has apparently been referred to management to assist, I am still awaiting the response. My bank account was being debited when I advised that I won’t have funds available, now the bank charged me R115.00 return unpaid fee which now put my credit record in jeopardy. I need a resolution from Telkom ASAP.
