I guess I just need to try to sign up again. 

I'm not sure if the kyc laws allow disclosure of why you are denied. Last time I tried, they had me resend my documents several times. After maybe 10 times (different pieces of mail). I got approved and was able load up my fountain wallet. A month or two went by and I found my account was 'under review' when I wanted to spend fiat to give a business sats.
