still waiting for a call back regarding incorrect billing

I have been incorrectly billed for the past 3 months, double billed and billed on the wrong date. Everytime i call, im advised a manager will call me back, a manager named Paul and Busisiwe. Its been 2 months already with no solution or call from the managers.

Telkom is honestly the worst when it comes to customers service and being a service provider. I would NOT recommend them to anyone
