I wanted to share how my story turned out.
Everything is fine.
I passed the verification process.
My account is fully functional, and I can withdraw funds.
I can also confirm that I didn't face any penalties.
After all the checks, I was told I could continue placing bets without any issues.
I’ve already withdrawn my money and will keep betting!
It's good that your request was granted. It's a lesson learned that when joining a good casino, use your correct credentials, so you won't have any issues in case things like this happen.
Still, many gamblers take these things for granted. They do this with new casinos, but it should be different for a more established casino.
The result may differ at other casinos; it's on a case-by-case basis, if another issue like this happened to other player this is a good reference.
