They took my id off me!?

i went out on friday night with my sisters driving provisional drinking. i am 18 next month and really wanted to go as i usually do so i took that as id. unfortunately one of the bouncers that knows me took it off me because he is a pig! i know its my fault i shouldnt use other people ids... but they sed that i could fetch it from the police station the day after (saturday) i rang the police station today and they have no Provisional that has been handed in. So i went to the pub and they wouldnt give it me. so how can i get it back? im not looking for a lecture of how its my own fault cos i already know that. But would like to ask you all.
