Telkom handed me over to debt collectors erroneously now I have to do all the work to clear things up. Absolute ****!

Absolutely shocking experience. Call centre agents are 100% unwilling help resolve my issue. Telkom made an error and handed me over for debt collection, I am now being bombarded daily with sms's, emails and telephone calls. No one at Telkom or MCS are vaguely interested in resolving this, other than to **** me out of R1000. FURTHERMORE MCS are charging me interest and ridiculous tariffs for phone calls, emails and sms's. I just keep getting told I will get a letter from head office that I now have to send to MCS. Why the heck must I resolve Telkom's ***** up in the first place?
