online bingo…i recon its a con?

Ive just played online bingo with bingoliner with a FREE £5 bet and won £45 on the first game…BUT i cant withdraw this money and I deprived a paying player from winning the cash…does this just stink a little bit? If I had won a £600 jackpot what then ? does anyone have positive thoughts on these games?

yeah derr most gambaling is but i see your point the computer at the other end could just see what u have picked and make sure those numbers dont come up!
