Absolute Poker Won't Pay Up

[Chino46]

I tried to cashout my Absolute Poker account. Their system wouldn't allow it because it's only $40 (I started with more). Anyway, I sent them email and they replied that their website clearly states you have to have more than $50 to cashout. I didn't notice this clear rule when I signed up and just now I went to their website and can't find it. Anyway, I just want what's left of my money returned and it's certainly not fair for them to just keep any amount under $50. Any suggestions? Thanks in advance.
