Unauthorized Deduction

If i could give a 0 i would, Im not even a webafrica contract holder, I just bought data for my housemates router only once then this company deducts R2000 from my account. I will be taking legal action against this so called business. I urge anyone who is considering buying from this company to refrain because my housemate who is the contract holder has complained numerous times about their service and products.
