Worst day ever

I took my my 12 year old son to fountain studios yesterday hoping to see the BGT final having got an email stating " you have now successfully received tickets to attend the recording of Britains Got Talent 2016 live final taking place on Saturday 28th May 2016 at 18.45". We live in Bucks so took about 45 mins by car and train and arrived at the queue at 11.15 am and were quite near the front - only about 30 people in front of us. I did explain to my son we would be waiting all day and might not get in, but he still wanted to go. Anyway at about 4.00pm our tickets were checked and we were given numbers and told we would be going in about 5.15pm. They started sending people away from the back of the queue as there was no chance for them and gave a number cut off point as to who could get in - quite a few behind us. At about 7.00pm they said they were really sorry but we wouldn't be getting in after all and a burley security man pulled the barrier across at the new cut off point - they only let about 20 people in. There was a huge uproar as you can imagine and many people still hanging about including a mother and daughter who was considerably older than my son and had arrived a lot later than us and were a lot further back in the queue, were suddenly let in as the girl was upset. I was furious and asked " why have you let that mother and daughter in when they were well behind us in the queue, I have a 12 year old who's waited all day, look at him" to which the man replied " there's nothing I can do". (By the way my son is small for his age so doesn't look 12 and yes I had ID for him.) he just couldn't understand how they had let this girl in and not him. - he was gutted. Absolutely disgusting to treat a young child in this way. He's even gone off a certain judge although it's not his fault. They should not be allowed to give out that many stand by tickets if there's only about 500 seats that are already given to production crew and contestants family and friends. Complete waste of a whole day and money to travel and park. Will deffinately not be recommending Applause Store to anyone or use them again. Very unhappy mother.
