Vodacom theft... AGAIN

A while ago I tried canceling my vodacom contracts prematurely, only to be told I have to pay more for the one than the other and when asked why, the lady on the phone said she can't tell me it shows on the system but she will get back to me, no one ever got back to me and I just continued on. Numerous times I've contacted vodacom to cancel a subscription for extra data on my contract and they continued to bill me for it and send me the data regardless. My contests are expiring now in June. I phoned in to let them know that I won't be upgrading because obviously I am unhappy with the service, they lady tried to persuade me but eventually took my answer as no. Knowing vodacom, promising things and not going through with it, I asked for her to email the confirmation that I'm canceling. She told me my last debit will be taken on July, which I don't understand because when I took out the contract, my first payment was debited 3days after it was connected. Nevertheless, I received an email with the heading "premature cancelation" on there my outstanding balance on everything is R0.00 my question to vodacom is, why, if accoridng to the bill you sent me, I clearly owe nothing, then why are u still debuting my account up until July????

I'm truly done with vodacom and want nothing to do with them in future and would advise everyone to steer clear aswell. It is the worst service, and call Centre agents are of no help. Not to mention after I phoned my airtime was all gone, and I had to phone in yet again, after explaining that I haven't been using the sim card since April, the lady said that there is a subscription to my name for R7/day that is why my airtime has been debited. I'm so fed up with vodacom, but I refuse to let all of this to. They are straight out *****ing and lying as the go along.
