KYC Issues and money stuck, it's $6,000

Deposited with a bonus here and beat the wager and managed to put in multiple withdrawals equating to $6000. I was asked to complete my KYC with Sumsub on two occasions as they somehow couldn’t verify me despite providing the documents requested all valid and in my name.

First time around I got sent a link to complete this and I told them it failed, so they sent me a new link to try this again with the same outcome and photos attached show the outcome of the KYC. I did forward documents to their support email which were then deleted and got this email-

‘Hi Scott

Apologies, we don’t process any customer documents manually, we use SumSub as trusted KYC provider. Please don’t send any documents over email, we will not be able to store and process those documents and will securely remove those emails not to compromise your information.

I also realised you are in touch with our support, they will follow up asap after checking in with SumSub.

Regards’

I have then received an email today stating the following -

‘Hi Scott,

Our trusted external auditor has not approved your KYC application. Unfortunately, we will not be able to reopen the link again or process any withdrawals from your account.

Yours sincerely,

The Dublz Team’

So my complaint is that they have not offered me an alternative way to verify my identity. I now have $6000 which I have won fairly, not breaking any rules, supplying correct information and valid documentation and they have just brushed it off and not offered me any alternative.

Just to state I have deposited in Bitcoin as my currency and happy to provide any proof of my wallet and where funds originate from.

I look forward to your reply.

Scott
