Dysfunctional Vodacom

Since being transferred over from Nashua mobile last year, Vodacom has been nothing but a hassle for me. Over charging, debit orders not being properly set, visiting the gateway branch almost every month. Now I receive a bill of over R4000 that is for a top up contract that couldn't possibly be more than R299. The accounts department tell me I will be debited and will address the issue within 14 working days. So I need to be moneyless while you play God with my money. This is unacceptable and the fact that I have to run around and sort out YOUR mess is disgusting.
