Telkom's bad service delivery

Struggling now for a year to sort out my Telkom account due to a change from ADSL to fibre. They charged me for almost 8 months for a line which they have taken out. After 7 months they came back to me and told me they solved the problem. I must just pay R7000. Then I dispute again after when they discovered another R2000 over charged. I made an arrangement to pay it off. Now my service is suspended to an arrears account. After spending 50 minutes on the phone at a Telkom shop, talking to a consultant, there was another R2000 over charged. He assured me the line is working again just to find out there is still no internet servicer. All of a sudden I have to pay another R1100 for this to be restored again. I will not recommend anybody to Telkom after my experience and after all the complaints I read on facebook of Telkom's bad service delivery. If I did not made an effort today (putting in leave for the day) I would not discovered the extra R2000 I have been overcharged.
