Cashed Casino - Verification and account issue

I played at Cashed Casino on November 15th and withdrew €638 of my own money. About four days later, the casino asked me to verify my account through numerous and various verification processes. I managed to complete all of them except for the transaction history section, which kept requiring me to upload it repeatedly.

I reached out to live chat for help a second time, but they weren’t able to assist me. Instead, they promised to get back to me via email. I specifically asked about the last required document, which was a bank statement that had to constantly be updated to the most recent date. The casino responded to my email inquiry in a very unhelpful manner—they simply directed me to the same place where I was supposed to upload the documents. :D It’s honestly quite frustrating as their responses were always vague and never addressed the actual issue directly.

After numerous emails and much back-and-forth, I finally uploaded a bank statement covering the last three months, showing the deposit to the casino as requested. Despite this, the bank statement was not accepted, and every time I contacted live chat, they promised to follow up via email—only for the cycle to repeat.
Finally, today, on November 22nd, I received a message saying the KYC process had failed, my account was closed, and my deposit would be refunded. This is incredibly disappointing, as I’ve been uploading documents and asking for assistance every single day, yet I’ve never received proper guidance or clear communication from the casino. Even i'm 100% correct sent bank statements right, and now feels so weird that account is blocked by failed kyc and even casinos didn't want to help with me.

Best regards,
