Vodacom are *******

Vodacom is the biggest ******** alive!! Im wifi contract was suppose to end at the end of August, went to my local branch, they gave me a nr to call to cancel my contract 1 month in advance, which was July, which i did! I was on hold for almost an hour, finally got through to a consultant,follwed all security steps, asked him like 10 times that he must make sure that end of August will be my last payment, he said no problem everything sorted, so end of August not only the final payment went off but extra R300! The stupid consultant didnt cancel the contract he UPGRADED it!!! *********** staff, bunch of *******!!!! I want answers, surely calls are recorded, and i want my money back!!!!
