Upgrade Delay

I upgraded my contract telephonically on 6th june, i was told by the agent that she cannot confirm the colour of the device, and was not given the option of choosing a colour. I was told3-5 working days for delivery. I phone today, 12th june, and am told that both colours are out of stock, and that phone might only arrive next week. I am also told that the black colour only went out of stock on the 8th, if i was given the option of choosing the phone that was in stock i wouldve obviously chosen that colour. so angry and disappointed with the service and (unnecessary) delay!!!
