This is the first time I’m hearing about this site and from the little search I did about them I found out that everything about them was a lie - once you enter the site they have a banner there claiming to have a perfect rating at casinoguru.com but on verifying it I saw that they had a rating of 2.7/10 and numerous complaints that remained unsolved.

I also visited BTCGOSU to see if they had a nice rating, so that @efialtis could try to reach out to them to come resolve this issue due to their reputation at stake but I also notice that they had a rating of 0.5/5 over there.

I doubt you’ll be able to get anyone to help you resolve this case and if you had carried out a little research on the site it would have prevented all this from happening in the first place.
