Try converting your proof of fund document into a PDF, I remember someone who complained here in the forum about their proof of funds getting rejected, and then someone suggested that he convert the files into PDF, after that I remember him saying that his proof of funds was accepted and was able to get his funds out of the casino. I could be wrong, but that is how I remember it.
If it was about the document type, then they would have given the reason they rejected it in the first place, but they did not.
Support told me every time that they would process my withdrawal as soon as KYC is done, 10 hours ago they finally accepted my 15th document sent!!!!
NOW they are delaying my withdrawal and giving me the same answer all over again. (no ETA , it will be done ASAP)
I just ask myself, what is their goal? Why do they want to use all this tricks to annoy clients?
I guess time will tell. Let's give it a few more days but to be honest, it's frustrating when you want your withdrawal As soon as possible, and they keep going in circles about it.
Are you sure that the documents you're presenting are having the same correspondence to your personal information, what I mean is if they tally with your identity and as that of the statement of account being presented, are you sure that the Binance statement of account you presented has made a deposit to the casino before, because I don't see why some of the provisions you made should be rejected except they do not comply with the normal standard of what has been requested of you.
They accepted the document as a supplementary one, according to OP. It means it sort of checked out.
