Amazing how many people seemingly know very little about consumer law.
As SaintBobby eloquently highlights, his contract was with the person/organisation that sold him the goods/service. He has no direct recourse against any third party involved, e.g. The venue.
If a consumer does not receive the goods/services 'as advertised' at the time of purchased then he/she is entitled to a refund.
It really is that simple.
Obviously, the retailer can dispute a consumer's claim but that involves responded to the original complaint/refund request at the time....
