Telkom - NO customer care or service

I have had two amounts debited to my mobile account and cannot get it resolved. We have a tiny fixed contract for R109.00 per month. We pay per EFT. We do not have a debit order in place. The amounts charged to my account do not belong to me. I have phoned, whatsapped, emailed, messenger, customer care centre at the mall to raise a dispute and have the amounts reversed from my account. They advise the debit order was unpaid. The account number quoted to me again which so called debit order was raised is not my account number. I send message after message, email after email to no avail. I get the same scripted answer over and over, notwithstanding which channel I use. Nobody understands English - neither written or verbal. I am receiving threatening SMS's via legal channels but nobody is prepared to assist/unable/unwilling.
