Vodacom Fibre is the worst service provider.

I raised a Hello Peter complaint against Vodacom last year due to inconsistent billing that resulted in my account being suspended. I got a call from a very helpful gentleman that rectified the billing however I never called to unsuspend the line. My account however was further billed for services not used. This was done despite my account being on a month to month contract with them so how does one get billed for services not used
