I can't wait to cancel all my contracts with Vodacom

Received my Vodacom account just to learn the 1GB data loaded to my cellular phone which was said to be R99.00 I am now billed R230.00. This is the way Vodacom operate and to find a solution via the telephone is of non-existence. Please don't sign into a contract with Vodacom as this will result in endless, problems. Their service is shocking, the only thing that works is their accounts where they deduct far more than they should and you as a poerson has agreed to.
