Not enough words to describe Vodacom's poor servic

I've got a dispute from May month with Vodocom...still not resolved(Almost July)!!! My data bundle ran out of bundle, I was not worried cause my perception was it would cut out when it goes out of bundle. With this dispute Vodacom send me an email and stating that I am on a My 1 Gig ... if you go to the Vodacom shop it clearly states I am on a 2 Gig package....what is now the truth and how can they have discrepancies with in their own system...TiRED of WAITING for any reply!!! POOR SERVICE DELIVERY. You can't talk to a person always someone else or a machine.
