Sick of vodacom

I have been struggling to stop vodacom from taking s box em off my account for the past few years. I closed my one number with them and the other I changed to 38rand contract as they said I will loss the number if I don't. I then saw that s box em is still going off my account. I tried phoning they just refer me to someone else saying they can't help me. After the third referral I was told to go back to the shop. Who already told me they can't help me. I don't even know what s box is but smart not able to cancel it. The number is S box em - ********** -4. I am so fed up with trying to stop this that I am going to shut down any thing I get from vodacom when this contract comes to an end and will never refer anyone to them. Antoinette a very upset to be ex vodacom supporter.
