TERRIBLE CUSTOMER SERVICE. AGAIN. FROM A LONG STANDING CLIENT

I really hate dealing with TELKOM. After 3 contracts I just have had it with the incompetence and frustration of dealing with these people. I have just received a call and SMS from Telkom saying my account is in arrears and my line will be suspended. This is all because they DID NOT debit me the correct amount on the 26 September as they said they would on the SMS they sent. I spoke to the call centre agent Simphiwe Vundisa. He admitted the error was on their side. They DID NOT debit me THE CORRECT amount as the SMS stated. He further carried on to say he is sorry BUT THEY CANNOT HELP ME. Even though its THEIR mistake, my line will still be suspended. Who has money to pay a week before payday? I asked for the matter to be escalated. He further continued to inform me his manager will also not be able to assist. Can someone in telkom clear this confusion? You did not debit me the correct amount as per your SMS. Why should I then be inconvenienced like this?
