Appalling Service

The worst experience. I upgraded online and instead received a new contract. When I contacted Vodacom, I was told it's a system error and they will be sending their courier (RAM) to collect the phone. The phone was collected from me on the 20th August and to date the phone is still on my name and on my Vodacom account. I have logged many calls with Vodacom and was informed that the phone has not been logged back in to their warehouse and until such time my account will be debited for the contract amount. The service that I have received is appalling. I'm now paying for a device which I don't have any Vodacom can't find in their warehouse.
