If you kept the chat in which they said the documents were verified, or anything else in which they verified that your documents cleared, I would bring that up to them and let them know that continuously asking for documentation is worthy of being considered a scam and even if it is NOT a scam, it's still spreading your personal documentation all around the interweb over and over.
Either way, I thought you had stopped to give it a couple of days. Don't you have another site that you can play on for the time being? Also, can you access your real money
ledger or account activity there so that you can verify your tournament buy-ins and fees that you paid? They'll likely pay it back as long as everything's okay.
