I’m not sure who to email or what to do for an appeal

hi, I am a self-employed individual in Washington and my last claim (from a few months ago) was denied, yet I know people in similar situations as to me who got some pretty life saving money. I have almost nothing now and am borrowing money to pay rent etc. I tried to call many times before but always received a blocked line with no chance to go on hold. Eventually I got burnt out and fell off of trying.

I’ve seen various posters suggest that an email was able to get someone to look at their claim, or a phone call to a particular place, but I don’t know what or where to do this. If anyone knows, could they please tell me?
