It didn’t work when I went to boom on line and had to ring up with a code I got given, did this, staff friendly and I paid the deposit. The next week when I checked my credit cards to my horror the full amount (a lot as booking for 6 people) had come off my card and a further £60.... quickly rang up in panic mode and they sorted it, putting the £60 suck on my card. The guy was really helpful and apologetic that it had happened. Lucky for us we could afford for the full amount to come onto our card but I’m sure there are families out there that couldn’t have that and it could have put them at risk of paying extra fees going over their limit on a card? Not noticing and paying twice etc.
