Complain to the Local equilivant of the ASA here in UK
Myself and another here did the same for a gash advert in Loop and we won. They were forced to recall the ad and never use it again.
Do the same in the country where you saw the ad, and get it removed. There is a thead on this same board about what we did in may entitled Ad in Loop may edidtion or something like that.
It was surprisingly easy to complain, and they could not back anything up.
