Telkom Bill

Telkom is the worst network to ever have. I had a contract with them from 20 June 2018. Contract was R705. I changed banking details now in Feb this year. I called the call centre they told me. I can't change it I need to in. Branch I go in the branch that lady told me that the banking details won't be updated for Feb so I stil. Need to make sure money is in my old Acc they will only deduct in. March from New account I agreed to that. March came they never deducted from new banking account I stil had the decency to pay the Acc for march I receive a bill of a R200 extra on my bill for debit order that bounced so now my bill was R908. I went back to the store were I changed my banking details they told me that the system didn't update they will sent my request to the bills depar tment. They gave me a reference number. I followed up 3 days there after reference was not assigned to anybody yet I must call again 5 day I called again my reference was assigned bt nothing was done when speaking to a guy he told me they will remove the R200 that was the begining of May he told end of May I only need to pay R706.10 which was happy with 15 May came they deducted R908 which bounced again that wa snot my debit date I called the call centre again they lady I spoke to say because the account was in arrears that why they deducted again that is not my pay date she wane come tell me of terms and cons I gave my deduction date the 25th and my bank charged me for that debit that bounced. The lady said that I must wait for new invoice and then see. I debit my account end of May for the R706.10 bt now my new bill is double the amount as they brought the R908 forward and again my account is in arrears like really now is this how u service your customers?
