Telkom's mistake, my time and money

I have migrated my data from Telkom to MWeb in 2016. During these almost 3 years now, Telkom has been charging me for data. I had to make innumerable calls and visited Telkom in Menlyn various times. My last call to Telkom with regards to the billing was on 20 Aug 2018. On 25 August 2018 @ 09:00 my ADSL line was cancelled. I do not have any internet at the moment. This morning (27 Aug) I was informed that I need to apply for ADSL again and just wait until a technician can pay attention to my application! Ridiculous! It was admitted various times that Telkom made the mistake, but I must go through the application process, and spend HOURS of my time to get Telkom's mistake rectified. And now I must wait until it is convenient for them to fix THEIR mistake!
