Competions Big Con's

Myself and my father both filled up at Bp a number of times, and entered there competition where we were told we had won, sports tickets and two for one movie tickets, none of which were forthcoming, even after submitting the requested forms and waiting double the requested time. The only so called prize actually received was a voucher for flowers which is given by the flower site for first time users in any case, so would have cost Bp nothing. I see a number of people have already complained on this site about this competition and I wonder how many others were conned but have not complained.
