An incredible story of customer service!

Dear Telkom: today you sent me a mail threatening to list me with the credit bureau for non-payment. Since the 1st of August last year I have been trying to have my line cancelled: I have mailed your cancellation address with the correct forms, I have followed up with your customer service agents, I have gone to your branches, I have texted your webchat helpers, I have even posted and inboxed you right here on Facebook with evidence of all of my attempts to cancel and stop the billing. Nothing has stopped you. You are now marking my attempts to reach you as spam. For nearly 6 months, you have continued to bill me for a line that I canceled on 1 August, and now you are going to blacklist me. I have never missed a bill payment, even yours, and now YOU ARE GOING TO DESTROY MY CREDIT RECORD and send debt collectors after me. Please, if somebody who works at Telkom actually reads this, please realize what you are doing here and help me prevent this from happening.
