Vodacom is messing me up

I have decided to cut ties with Vodacom. They deducted R748 from my account this April. I do not know for what as the only data I got from Vodacom was free data as confirmed Elizabethon the 02 of March as they failed to correct their wrong as promised.<br> <br> I have instructed my bank to reverse it. I have no data. When I call the head office they toss me around. So I have sent them an e-mail cancelling this contract with immediate effect. When I spoke to Pathlu she told me that I now have a contract for R199 subscription with Vodacom and it is not a data contract. All I want to do is cancel this contract.<br>
