Bouncers LIFTED MY DRESS UP! and wd my legs around them!?

ok so I got a new job working at a bar i have been there for a month its not very cly but it will do for now. Anyway last weekend i got pretty drunk and went out to the bar i work. the bouncers on the door a very cheeky . the type that slap girls ***'s when they walk in. but this time it went too far. i was stood at reception and two of them came over. lifted my dress up. ( i had a tiny thong on.) picked me up put my legs around them and started jumping about. they put me down and did it another 2/3 times. i was fuming! they took full advantage of me being drunk . it was very disrespectful and i cant stop thinking about it. i have seen them since and made them say sorry but it wasn't genuine and im not satisfied. what should i do? my mum even said press charges. im only 19 and these are like 40 year old men. ? help please.
