No communication!!

About 2 years ago, I had an issue with an invoice that Vodacom sent me with regards to cancelling my Fibre contract. The issue took about 1 YEAR to get rectified. While I was in this back and forth with Vodacom, they decided to hand over my account to attorneys for no payment!! Keeping in mind, when I contacted by these attorneys, my account with Vodacom had not been rectified yet. when I contacted Vodacom to express my complete outrage that I am now liable for legal fees for negligence on Vodacom's part. Vodacom then responded stating that I should pay what I owe Vodacom, and they will sort out the rest after I send them proof of payment. I have done this. Vodacom has not responded to me yet and I find this completely unacceptable as I have done what was required of me and Vodacom has dropped the ball yet again.
