Advanced learner loans

I applied for the Advanced Learner Loan on the 22nd July. I had to send off my birth certificate as I do not have a passport. I sent it off just a few days after sending the application and I've just received an e-mail from SFE saying they're still waiting for my evidence to be sent. Is this just automated or they genuinely still don't have it? If they don't, I have nothing else I could send because I sent off the only piece of evidence I have possible. What should I do? Wait longer due to timestamps or call up SFE? I don't know what to do because I go to enrol on the 21st August for my course properly and I need this sorted by the time my course starts.
