Boomerang-bet Casino - Refuse to validate non custodial wallet

Hello,

Throughout all email exchanges with Boomerang.bet, I have successfully completed all standard KYC checks requested (identity and account verification).
These KYC checks were completed within the last 40 days, and no further KYC issues have been raised since then.

The only remaining issue concerns verification of a non-custodial crypto wallet and the related deposit, with a balance of €3,300 currently blocked as a result.

For wallet verification, I provided:
• A signed transaction/message created using the private key of the wallet
• The signed message explicitly included my full name, the date, and the internal ticket ID, to clearly demonstrate control of the wallet
• A public blockchain verification link confirming the validity of the signature

This is the only technically valid method to prove ownership/control of a non-custodial (decentralized) wallet.

For proof of deposit, I also provided:
• The transaction hash (TXID) of the deposit
• A screenshot of the deposit, clearly showing that the transaction is linked to the same wallet address

Additionally, I explicitly asked whether I could provide a video recorded with a second device, showing the wallet open on my phone and demonstrating real-time control of the address.
This question was never answered.

Despite all of the above:
• Responses from Boomerang.bet have been consistently delayed, taking around 5 days each time
• Each response is a copy-paste of the previous email
• No response addresses the signed message, the TXID, the screenshots, or my concrete questions
• No explanation is provided on how ownership should be verified for a non-custodial wallet

At no point has the operator:
• Explained a technically feasible verification method for this wallet type
• Clarified what proof would be acceptable
• Addressed the evidence already submitted

This situation is particularly inconsistent given that the operator accepted my deposit from this same non-custodial wallet without issue, yet now refuses to validate it for withdrawal purposes.

I have made repeated good-faith efforts to comply with all requests over the last 40 days. However, with €3,300 blocked and no clear guidance provided, compliance has become impossible.

I respectfully request that this case be properly reviewed and that a valid, applicable verification method be accepted for a non-custodial wallet so the withdrawal can be processed.

Best regards,
Jose
