Vodacom ******* - Debit your account after you cancelled contracts.

I cancelled my contract in the middle of February and was told that a debit would still go off the end of February because it was too short notice. I said OK, that's fine. But then they decide to debit me again the 28th March and for some reason, NO-ONE CAN ASSIST ME IN GETTING THIS SORTED. The number is prepaid already so I can't call the cancellation department and your accounts department doesn't answer their phone. I suggest you contact me and sort this out ASAP!
