I have faced this issue with Betinasia myself which is annoying to say the least, but it's worth it considering their epic odds on so many markets. However, they keep requesting KYC again and again randomly which is a big issue with them.
How many accusations against said casino are legit though?
Just one legit accusation is enough to screw their reputation and there is one horrible one where they stole the user's deposit in a scammy manner. They aren't trustworthy or reliable in my opinion either.
