Overall bad service

This is actually a review on a few issues. 1. Bad customer service. Just horrible really. On more than 1 occasion I've has to wait for over a month for my query to even be addressed. 2. Call centre. I can't tell you how many times I've been on hold, only for the person to \drop the line"once I EVENTUALLY get through. 3. Billing. I've been overcharged on 3 separate occasions on my contract. Each time they reverse the charges. But the fact is that they are overcharging me without ANY sort of notice. The only reason I stay with Vodacom is because of the network. Their customer service is one of the worst I've seen/experienced in SA"""
