I have been contacting my US Congressmens office, but getting nowhere

I am not a federal worker, but I am a veteran affected by the firings ot the VA. They fired caseworkers that handled community care referrals. There is currently a single caseworker who gets 900 new requests for referrals a day. Ive been waiting on an emergency opthamology referral for 3 weeks now.

There were two that I saw reported, Pamela and Jason Riddle
