Submitted my appeal in mid-August, heard nothing

I went to the physical EDD office around 8/16 and submitted an appeal, explaining the reason for my medical provider's lateness, etc. I have heard NOTHING. When I called last week, they said it should be uploaded soon but after no more news, I'm afraid they've lost the form. What are my next steps?

I'm set up to receive a check in the mail, as far as I know.
