We had booked tickets for a show. 5 days in advance we received an email saying the venue was changed to a new venue 15 miles away. Not ideal but fine. 4 days before the show we received an email saying the show start time has changed from 7pm to 5:30pm. This was difficult as it clashed with earlier activities and incurred extra cost, but we made it.
Show time was advertised 75-90 mins. It was 45mins.
I want to complain that the service received was so far removed from what was promised that it represents a breach of contract, but I don't know if there are any trading standards legislations etc that I can quote to back this up - my googling isn't throwing anything up! Can anyone direct me to any good resources about how to get a refund after an event has taken place if it was significantly not as described?
