I booked a trip to jump xtreme for my daughter and 5 friends for her birthday through groupon, saturday was the only day that everybody could make it and the only time available through groupon was 6pm, everybody was happy so it was booked to find out a few days before that jump xtreme was closed! There was a private party and groupon were informed not to take bookings. After ringing the other parents the time was changed resulting in one child missing out, this was obviously upsetting, groupon offered credits so I told the kids we would go again in a few weeks so the child that missed out could come too but I still took the others to avoid further disappoint and it was too late to book anything else. Now (after we went on saturday) groupon have said they will not issue a refund as I used the voucher even though they did not meet the contractual obligations and it was not stated in the email that I would have to cancel my daughters birthday treat all together. This was the first time I've booked through them and I would never use them again.
