Telkom ripoff customers

My account was overdue but was subsequently paid on the 23 May 2020, and despite numerous phone calls, visits to the local Telkom shop, and messages on social media, I still have no access to phone calls or data. I am losing business daily and I plan to make a claim against Telkom for this. I have been told the best route is to take this matter up with ICASA, which I will now do.
