dissatisfied client

Vodcaom has the worst customer care line. I reached out to Vodacom after being told that my account is in arrears of over R2000+ and my contract is only 3 months old. The customer service consultant in the billing department failed to provide me clear answers and was very rude even after I alluded to her that I am only seeking clarity on the matter as it did not make sense to me, she went as far as telling me "Vodacom did not call me, I called Vodacom!". Now I must pay for arrears that do not make sense to me.
