VVM review: Information

Telkom erroneously billed me, the issue has been resolved, I have forwarded all the emails to [protected]@vvm.co.za. now they want 6 certified signatures, for what? I can only imagine what fraud that will be used for. I get harassed all times of the day and no one is willing to accept there is no outstanding payment here at all.

I fear I will have to go lay a charge of harassment and fraud against this company. Please advise what else I can do as this is really stressing me out
