MTN USELESS

Hi i am so livid at this company last year about june/july i got a contract with MTN then round about September to October i was on short time working maybe three days a month which for obvious reasons my account went into areas by three months but that is not the big thing for all the time not once has MTN tried to debit my account to try and furthermore not once have they tried to contact me to find out what was wrong that I was not able to pay my account... Roughly about three months ago i heard my manager speaking on his phone telling the person that he was not Thomas and i asked him who it was he said its somebody from CSS collectors i spoke to the guy gave him MY PHONE NUMBER which he did not get from MTN and that's when i found out that my account was handed over and this like i said without anyone from MTN contacting me nor debiting my account i have settled the outstanding amount about two months ago with CSS Credit Solutions and last week when i checked my bureau my the account shows default and the full outstanding amount is still showing as if i did not make any payments yet i received a PAID UP letter from the collectors which after almost an hour of trying to get through to MTN offices on that useless 083 135 number that puts you in a loop over and over you never get to speak to any agent i got hold of one named Lesego Tsele at MTN and found out that Their collectors named CSS has not updated my account with MTN which is their duty as they are they collectors i then emailed the PAID UP letter to Lesego Tsele last week as my mail shows this morning 8 days ago i sent him a mail yesterday as well to find out what is happening because my bureau is now showing negative because of this i mean i settled this like i said almost two months ago and it still says i owe the full amount and yet no one from MTN has contacted me to let me know what is happening now i have to sit with this on my credit bureau is that fair i am going to contact the NCR today because they got their money and they don't care any further about their client
