Poor service

Upgraded contract.Waiting for Skynet to deliver after receiving a date for delivery with pin.Just to wait all day long and nothing pitched.This was on a Friday 25/06/07 just before the long weekend.I cancelled my trip and waited until 20h00. This morning after struggling for a hour to get hold of Skynet to find out what is happening because I have arrangements and need to know if I must still wait.Just to be told delivery will take place on Tuesday.Why give a date and time and not letting me know that they are not coming anymore.
