Poor service from Vodacom

After 5 months of following up on a query I logged with Vodacom I've been told that there is no reference of a query. I went back to the Tygervalley Vodacom branch today for the 5th time. The one Consultant walk out the shop after he told me to wait while he finish with another Client. The other Consultant just keep telling me he can't do anything for me and that I must call another Vodacom number. While I had someone from Vodacom on the line I could not get hold of the Manager or any Consultant that could talk to her. The service sucks and I'm definitely considering closing my contract.
