Vodacom gives bad service

Vodacom still has not made contact with me even after saying they would. They say they have tried, but I have not received a single message or missed call outside of Hello Peter. Their communication with clients is shocking and the service offered is expensive but sub-par. I have never had a good experience with Vodacom as a service provider. The take airtime in leui of data when they shouldn't and then blame it on the consumer.
