Upgrade Non-cancellation

So after confirming that I could return my upgrade within two weeks if I changed my mind I upgraded. Then I informed the online store on 29 Oct - after a 30 minute phone call and being sent through four different service departments - who said they would pick the phone up on 30 Oct, so then nobody picked it up on 30 Oct, the date was changed to Monday 2 Nov, and nobody picked the phone up, then it was changed to Wednesday the 4th and nobody picked the phone up. <br> <br> At this stage I'm so sick of dealing with this company that I'm cancelling my entire contract, heaven only knows how long that will take based on current events.
