Vodacom is *****ing from me

Vodacom keeps on billling me with charges which I did not incur. We've sorted out the problem last month, without them giving back my money. This month, low and behold, I am billed with the same charges again. And they are not able to fix the problem, and I am forced to pay the monies. This is *****ing and the people working there are ***********. They can't fix the problem, they do not refund. This is *****ing. What are they funding with our monies? *****ing *****ing *****ing. *******
