Disgusting service from Vodacom!!!

Vodacom.. I had a tick a star, i wish i could give you ZERO stars!!!! Extremely disappointed with the service from Vodacom. We cancelled our contracts approx two months ago, we received a call from vodacom to confirm we will be going over to prepaid and when we received a bill last month we phoned and was confirmed our contracts were cancelled as we weren't on their system any longer… only to receive a 2nd bill AGAIN and when we phoned today Vodacom confirmed that Vodacom cancelled our cancellation request and will have to submit another cancellation request??

Why would you as Vodacom decide to cancel our cancellation request? Who gave you permission to cancel our cancellation? We will take this further if not resolved urgently as this is unacceptable!
