hahahaaaaaaa good luck

LOL. Funny question / avatar combo.

i’m not sure but it might work but if its online no. You will not get you pounds back from playing an online game.

More fool you playing roulette on line. Much more exciting and more fun on a real table in a casino!

At least you can have the pleasure of seeing your chips physically going down the loser’s shute as opposed to just watching them disappear off of a monitor screen!

Well, you shouldn’t gamble money you need.
You could say your child was on your PC and a tab was on the tool bar on this website and somehow managed to lose £300. They may not give your money back but you can report websites if they are cheating. If all above fails I suggest you tell your family, say you didn’t think it was for money. Better, tell the truth.

Doing a system restore won’t get you your money back, but getting a time machine and going back in time might just do the trick.
