****ty service, couldnt deliver a takeaway let alone a phone

I was offered an upgrade to my cell phone contract, which I accepted. I was told that it would be delivered by the 18/11. it was not due to them not having stock. On the 20/11 I was then informed that it would be delivered by that day but to the wrong address, I informed the courier who informed me it would be delivered that day to the correct address, they failed to deliver. I have now been put in a position that the phone will be returned to vodacom. As far as I am concerned they must take their phone and contract and shove it right up their ****
