No assistance from Vodacom on double billing problems and billed for non-existent service

I have a major problem with Vodacom as I have logged 2 incidents regarding my fibre installation where I got billed double and also getting billed or VIOP service that is non existant. I have followed up 5 times on the 2 incidents and I do not get anywhere. In the mean time vodacom goes bos and keep on billing the living daylights out of me. You guys for real....you offer a service, then when we take it, you double bill us or bill us for a non existent service and then you refuse to assist when we point out the problem. If I don't pay my bill then all my services gets suspended, which means this dumb idiot must keep on paying while vodacom ignores my plea for help. Seriously, vodacom, it is time for some good competition where we actually gets help when we ask for it, also a company that will look after their clients, quite the opposite as greedy vodacom.
