I agree that it was a very unprofessional way of doing things. No explanation or anything. As I said in my original post I was worried sick so hearing someone else is in the same boat as me does make me feel slightly better about things.
I know they say they only re-imburse over £50 UK travel but the cancellation is their fault not yours so I really hope that if you explain to them the situation they have left you in they will try to acommodate you.
Absolute worst case scenario I live near Heathrow and my Sister lives near Bournemouth so I'd be willing to put you up and help in whatever way I could.
Obviously as soon as I hear anything I shall post on here. Either way I'm still going up that damn tower. How often do you get a chance like that?
Once again if anyone else is in the same boat or has any experience or insight into our predicament it would be most welcome.
