Contract Cancellation

<p>My contract with Vodacome came to its end months ago. I kept the sim for a few months, using the data and getting charged for it. Which makes perfect sense. A couple of months ago I called in to cancel the contract and was told it was...I got charged via debit order the next month thinking maybe it would be the last charge. I then got debited again and called in to cancel the contract. The person I spoke to assured me it was cancelled. I see I have been debited again this month. So I've been charged at least 3 times since trying to cancel my contract. What irks me most is that I will not get my money back and if I call again I'll just be told its cancelled again. </p>
