It all depends on the validity of your documents.
If they are all in order then you will get your money but it might take some time.
The best thing you can do is to wait, don’t stress yourself and be prepared for it to take some time. If you get in a negative mindset the you will stress yourself out unnecessarily.
Casumo will be looking for any reason not to pay you - breaching of bonus terms, dodgy source of funds etc. All you can do is comply with their requests. Stay very calm when communicating with them, don’t give them any recourse to, later on down the road, give the impression that you were the one been unreasonable.
Give them time to verify and validate everything. If the outcome isn’t ultimately beneficial to you then you make a formal complaint to the casino, await the final response(which they are obligated to provide) and then, depending on that response, you go through an independent complaints service. Don’t get ahead of yourself though, there is no point fretting about a negative outcome that may never arise.
