Useless service from telkom

I took out a contract in February 2018. Ever since Telkom is giving me problems. If they don't over charge me then they want to charge me for a debit order that has rejected (cause the idiots decided to debit the wrong account) I had to do a EFT payment!!!! Not even the bank charged me for a rejection. I'm calling the call center which is more useless then anything else. On Saturday 12 may 2018 I called and spoke to Mbali Simelane and she asked me to send me my bank statement to show I had money in the account and that she would escalate it!! Today the 14 May 2018 I call again to find out how far it is. Nothing has happened I waited on the call for 30 mins. When I wanted to speak to a manager (which they are forever busy) couldn't speak to one coz the call dropped!! I'm so gatvol of this bull****!! Fix my debit order. Don't charge me for this that is not my fault!! I didn't say you're must debit the wrong account!! I WANT AN ANSWER BY TOMORROW!! I WILL MAKE TELKOM NAME SO BAD!!
