No S7 delivery!!!

I ordered a new upgrade S7 on Friday the 11th March on *** (a premature upgrade) I was told the phone would arrive the following week, definitely by the Friday. I was eager to get the phone seeing that the free VR headset offer from Samsung expired on the 20th. The phone DID NOT arrive by Friday. I was told to phone on Saturday which I did. Subsequently I wanted to change the delivery address from East London to Cradock....a task that is/ and seems to be impossible to Vodacom staff. A lady assured me that she would phone me on Monday the 21st...still waiting!!!!! Another operator said that the previous lady was not in hence no call! <br> Well I still wanted the change of delivery address. The operator suggested that we cancel the previous deal and that I get in my car and drive 145km to Queenstown from Cradock to purchase one in store...of which there is no gaurentee of stock or that they would grant me a premature upgrade.<br> So here I am in Cradock with no upgrade, no idea when it will arrive.
