Telkom is a terrible service provider

Terrible terrible service provider, will never in my life do business with Telkom again. A product was wrongly sold to me and wrongly billed to my account in 2020 and I am still trying to sort it out. They claim I owe them a subscription fee for one month and added a lot of fees to my account for not paying the subscription of something I never received. They now handed me over to three different debt collectors / attorneys and still the issue is not resolved. The amount has now tripled as they just add fees to it. I have so many case numbers from Telkom and communication with the debt collectors but still nothing has been done or resolved. At the end I sit with a bad credit record or a bad name because of this and I have never missed a payment or short paid on anything in my life. Telkom has very bad service or I will rather say no service and the call center is a waste of time, they cannot resolve anything. Does anyone know of someone who can assist me with this matter, I am desperate.
