21 grand casino don't want to pay!

Have a problem with 21 grand casino withdrawal.
I was asked to send my id and utility bill to finance department. I did and there problems started. The problem is they can't open these pics.Then I send it in jpg, bmp, png, gif, pdf, doc formats. They told me the same story . I even uploaded these docs to website but they can't see it as well. It's the lie. I sent this documents to my friends, everybody could see but they don't. I can't give a public link here for security reasons but i would do to somebody who could help me with this situation. So you could see everything is fine. I'm sure they just saying that they can't see it because they don't want to pay.

So what i should do next? Any ideas?
