Incorrect Billing

I have been calling customer service to find out more about been charged penalties every month ,I get promises to every consultant I speak to that they will look into it ,the package I chose is R369 per month but now every month I pay close to R650 ,I demanded to speak to their leader and the guy called Mlungiseleli Jonas said she is at a meeting,she will call me ,Its been 3 days now ......nothing.

I've been a Telkom customer for more than a decade ,loyal but Telkom is treating us badly and no customer service,I'm very disappointed ☹️☹️☹️.
