No communication/ and bad service

On the 13.02.2018 I decide to call Trans-union and esquire about my credit, to my surprise Telkom has defaulted me and claim to have written off my account due to me not paying. The last time I had from Telkom was a year ago and I was cancelling my account due to the bad service I was getting, and I was told someone will call me to provide me the outstanding balance. Till this very day no call from them except me calling.

And today I am being placed on Default without them contacting me nor making me aware of the no payment. When I called to my surprise they still have all my details correct and the lady(Simxabisile) I was speaking to confirms that the is no trace of any communication Telkom has done with me. This means if I never contact Trans-union I was going to be BLACKLISTED without any of my knowledge .

My ask is I why was I placed on default without anyone contacting me?? And it stats account is on write off, which is really annoying because I cancelled the account personally. I WANT TO BE REMOVED FROM DEFAULT YOU HAVE PLACED ME ON, AS NO ONE IS ABLE TO UNDERSTAND WHY WAS I PLACED THERE WITH NO COMMUNICATION!!!.
