My wife purchased 2 Groupon vouchers for a family kayaking activity (for my birthday) in Brisbane. We booked via Groupon's online booking tool and received confirmation email.
When we arrived, the business had no record of our booking. As the session was fully booked we were turned away. We then had 3 hours to kill until our dinner reservations.
I contacted Groupon immediately and explained the situation, asking for a refund as my birthday had passed. We spent the next 5 weeks writing dozens of emails and using the online chat function. Groupon used lots of dishonest tactics (changing reps in the middle of online chats; failing to respond within timeframes they promised; offering a credit on their UK website!).
They have begrudgingly agreed to a full refund after threats of legal action were made.
You don't need to take the risk of using Groupon. Please learn from my mistake!
