You could try to open a ticket on guru casino and they will help you to solve the problem, or write on the casino thread to get the attention from the staff.
But the ideal way to fix this problems is directly with the site support because not all the casinos have the support guys on this forum. If I were in your situación I would send the a mail.
I tried to ask in live chat an opportunity to send all the needed documents but no answer from them. I will try guru casino ty for advice
They are active 24 hours according to their website here
https://bc.game/help/contactusYou have a question? Can't find the answer on the website? Don't worry! you can contact our 24-hour online customer support any time, Our customer support team is happy to answer any of your questions.
I was looking for an email address as sometimes it's easier to communicate through email as you can attach all the necessary documents, plus you still have some trail of conversation since you own the access in your email, unlike with inside the casino where you'll lose your access once your account is locked.
Actually they also have a forum, maybe you can post your concern their too.
