I tried in vain to book a party for my son some time ago with a trampolining centre. I had to postpone 3/4 times, as various people couldn't make it. Parents didn't respond to my requests to confirm dates either, which didn't help. I wanted to scrap the whole thing as it's a long way to go and no-one seemed willing to commit to the party. I had to book a 'slot' to reserve a time for the party so I could tell parents when it would be. They don't take a deposit - expecting you to pay in full when booking.
When I spoke to the centre to ask if I could cancel and get a refund as I just couldn't get the party sorted, and pointed out that I had tried to reschedule several times, they refused. I explained that I just couldn't get people to commit and that this was a lot of money for me to lose. All they would offer was vouchers to use later. I don't think I'll ever go there as the kids are now on to the next fad and it is quite a trek to get there - we hardly ever travel that way.
Do I have any redress at all?
