Billed for two contracts that I do not have.

I upgraded my contract to RED VIP with a device. I then cancelled the contract when the device arrived as I was not happy with it. Vodacom collected the device. This was done within 7 days as stipulated on contract terms. To my surprise the contract was never cancelled even though they collected the device and said the contract will be cancelled. I discovered when I received my statement which indicated that I owe vodacom two contracts that amount to R3500. On the statement I saw my old contract and the contract that I canceled and didn't have the device for it. I called in immediately. They promised to log a call with their so called back office to correct that. A week later, that was still not done. I called again and they gave me another promise which they failed to honor again. I don't know how many calls I made to vodacom and to date, my account still reflects ridiculous amounts that I am due to pay end of October. I received sms that someone has stopped this but this is not true.

I will not pay for the lines that I do not have. This is complete madness. Vodacom must just look for new staff willing to work and resolve things not the current staff that is *********** as this is affecting us financially. Who can accept to pay for a contract and a device which vodacom confirmed receipt of? Can this be resolved please and can I get my refund.
