Disgusting Service from Telkom

I moved from my address in April 2018. I requested from Telkom for my line to be moved and I did not get a new line installed. I then moved again and made another request for my line to be moved to my current address in Gauteng. I still did not have a line installed. I was without service from April 2018 until September 2018. I was then told that even though my line was not in use I was liable to pay and in order for them to move my line I paid account of R3000. I was allocated a technician to install my line on 19th October 2018, who contacted me but then did not complete the service. I still had no line installed. I was so fed up that I cancelled my Telkom account and was not refunded for the payment of R3000 even though they said they would. Now they have me listed on the credit bureau and their system as having an unpaid account for almost 3 years now.
