Upgrade cancellation and Revert back to the old contract.

Faulty Devices and bad customer Service. I was recently offered a new devices by Vodacom on the phone. I was due for an upgrade. Vodacom called me to offer me a couple devices. In this package there was also an HP laptop included. This laptop not working(faulty). I called in for it to be returned, but due to a bad customer service and unwillingness to assist I ended up asking them to come and pick up all the devices and revert back my contracts with them as I was soon to finish paying up my contract.
