What are my rights? (Service not/part received)?

What are my rights? (Service not/part received) UK?

This may sound stupid but me and a friend paid for service that advertised to include:

SOFT DRINK BOTTLES ONLY ON BUSES ;TICKETS - £30 (INCLUDE ENTRY & QUE JUMP INTO NIGHTCLUB)

When we got to the club we where my friend was not allowed in for being too drunk which I disagreed with and stayed out with him, he was told he would be allowed in after x amount of time which was not for-filled by the door staff. I did ask to speak to management at the door and this was promise but still not acted upon on the night. I did try to get into the club as I was allowed before but was then disallowed because they had believed that I was thrown out and not left on my own behalf even though I still had my £30 ticket to enter the place.

We had to wait for 4 hours in the cold before our bus returned, we got advice from the person who handed our tickets to email the club directly which I did the next day.

The fact is we paid £60 between us to stand out in the cold for four hours not including the time spend travelling to and from the club which is a good hour or so away. I believe that I did not receive the service i paid for a would ideally like the refund of the money as I get paid min. wage in my job, that is a full days waves for me which I feel robbed off!

What action should I take to ensure I get a refund of the money? Emailing the club at the moment but they seem very reluctant to pay me back anything and are only offering to be put on the "Guest List" next time I go there but believe I should be offered more.
