I'm glad that your case has been sorted out and you have received a clear update on you situation. Hopefully, your withdrawal will be released within the specified time frame they've provided.
Also, If I were you, I'd stay away from that platform and never try to gamble there again. This is bad behaviour they are showing especially how they process things. Most platforms process KYC within the day or even before or after 1-2 hours. Also, by then your withdrawal should also be approved and process right away to avoid any delays as accusation like this could arise and damage their reputation. This shows that they don't care about their reputation.
