Telkom Worcester Store

Telkom made a mistake when I was in store (they admitted it was their mistake). The result was my bill was R2000.00 more than what it was supposed to be. I immediately reported it when I received my bill beginning of August 2020. It is now almost 3 months. They have taken the money. They do not give feedback. Case has been logged etc etc. I have tried the Worcester store where the mistake was made, the online chat, email, the phone number of Telkom . I think *******ion is a term that can be mentioned now.
