We had Telkom install a fibre line in June 2020, it was a special for R499 with first 3 months free including installation. Last month we received a bill saying we have to pay for Sept and Oct. We paid the amount for Oct only. Today we get a bill that says they have made adjustments to our account (no explanation) and we owe them R1514 to be paid by I Nov. We have tried every single number on their website to try and sort this out. None of the lines are working. How do we sort this out??????
