No help what so ever!

I called in today to try and get someone to please cancel my upgrade, just to be told it's impossible for them to cancel, no questions asked! The upgrade deal was done yesterday after 4pm, no delivery has been taken or anything of that sort.<br> What makes this more fustrating is it took 20mins of holding just to gte no assistance, when I asked to speak to a manger I was put on hold and for another lenghty period and then there was no response.<br> <br> I don't want them to come deliver anything to my work address, I want ot go into a store and get this upgrade done that way since I need the phone asap!<br> <br> Can someone please resolve this matter for me.
