I am now taking the matter to the Ombudsman as Im tired of Telkom

Im absolutely sick and tired of the telkom contract and require assistance to have that closed with immediate effect , failing which I will be taking matter to the Consumer complaints Ombudsman as I can longer deal with the *********** , impatient and unprofessional staff at Telkom. I have an Wi-fi account where I am to pay R199 / month.A few months I had changed my banking details , did advise for the debit details to be changed where they had failed and telkom continued to debit the old account , inturn charged me R200 for unpaid debit order . Fair enough I have made a cash payment to my where my account had R799 outstanding . After I had made payment directly to telkom , the debit order once again went off my account and debited the money which had been meant for other use . I went to a Telkom shop at Cornubia mall to query why was i debited after I had made the cash payment , the consultant advised that my account will be in credit for R799 and would not have to pay for 2 months . Today I have received a statement dated 01 May 2018 stating that for this month I will be debited an amount R603.51 , on the statement the debit order amount of R799 does not reflect .Only the amount that was deposited paid in cash on the 10th April reflects . Where has the debited amount gone to ?I need for this to be sorted immediately as if i do not receive a resolution to this case I will be sending the matter to the Consumer ombuds as I cannot continue having Telkom suck me of the little money that I have . Im waiting for your call
