VODACOM THE *******

Vodacom stole my money and doesn't want to refund me. I cancelled my data contract end of June, by the 4th of July I didn't receive confirmation that the contract is cancelled, I called them again and only then the contract was cancelled but I was charged for a full month for data that I did not used and the customer care lady assured me that I will be refunded because Vodacom did not cancel my contract the firs time I called them. Vodacom, you are *******!!!!
