Vodacom charging for device not received

Upgraded my contract months ago. Did not receive the actual phone, was sent to the incorrect person. With back and forth battles between vodacom and ram, eventually vodacom canceled the contract in order for me do to an in store upgrade. Was sent a invoice from vodacom charging me for the cancelation of the device. It's just pathetic how they have wasted my time in sorting this out and yet I still don't have confirmation that it has been resolved. After this contract is done I am done with vodacom
