Telkom billing

I took out 2 telkom cell contracts in March 2017, a week later upgraded my home phone ,to a adsl and took a package on special. Telkom , billed me for installation on both Cell and adsl contracts, I queried it with no result from them from June 2017, every time it got escalated. In September 26th they blocked my line Adsl and after making a big issue with accounts, theyre cancelled and refunded me my account , on Adsl, A week later they suspended both lines on cell phone, claiming I owe them , they tried to debit my bank account and I stopped the order , over two months consecutively , I kept paying my contracts with no use of the phones. I phone call centres and spoke to managers who emailed me making promises to sort out the billing from back office. It is now January 2019 and nothing is being done to fix their problem. To make matters worse I now get billed on my adsl line for a re connection fee of R275+ . No one is Telkom is prepared to sort out the issue or even re instate my cell until the matter from their side is resolved. I inquired as to how to cancel the contract, even their Telkom is not helpful! They are going from bad to worse. A simple billing problem cannot be solved, by so called back office.
