Withdraw delayed due to no verification delayed

The verification process is slow and, besides ID proof, proof of adress took ages but finally was accepted. The problem is with the transaction proof. I did a deposit via Jeton (e-wallet), after several prints sent via email (without a response) and uploaded via site - it was finally accepted. After that they asked me proof of my bank transactions to prove I did a deposit to Jeton - again, several times I uploaded that proof. Until yesterday, my account wasn't yet verified and so the withdraw requested (500eur-maximum permited, I have another 200eur in my balance). Today, for my surprise, I noticed the site is not available anymore (I dunno if only for Portugal since I dont use VPN). For 2 weeks I registered, played there and could enter the site. So basically now I have 700eurs I can´t withdraw and an account with personal data that I can´t even access. Any contact via e-mail was never answered. This was I have no solution but make a formal complaint here. Please help. Thanks.
