Did you click on support where there was an option for a refund ... I think.
From all the customer queries I've seen on this forum, the support has been quick & flawless. I think it would have been better to contact them privately before starting a thread. They might have been able to help you.
Regarding the game, the LDW games are the only ones that hold my interest months on end. I've bought other fast games that seem more interesting at the start, but then get quite repetitive after a while and I never play them.
Everyone likes something different. 1 hour trials, or even 30 minutes are the normal thing, so I don't think you can fault them for that. Maybe reading a review before buying might be better so you know what the game is about.
