What you need to do is to contact support for the site and find out what's going on.
What site was it? Do you have a hand history? Did you note down a hand reference number? A table id? The opponents name? Did you complain big and loud when it happened?

I mean why are you posting it here? At best we're going to call you an idiot for not doing something more about it than whinging here.

At worst we're going to call you a liar.

Somewhere in between maybe you're an idjit who got all confused about what's going on.

But really if this isn't a load of crap then not doing something about it is just plain stoopid.
