TS where you are? Did you solve your issue? I know the feeling when you won something but you can't make your 1st withdraw, really. We've all been there lol. But you just started the topic and then disappead.
If you were playing on SportsBetting site (Chico Poker Network) and won something then you should make a deposit if you want to withdraw. But after doing that you'll be able to withdraw with no problem. I used to play there (Tigergaming, the same poker network). Never encountered any problem. Even though I rarely play there now, I know this network is trustable.
