What do I do now that the VA denied application for aid and assistance?

Started this in March 2022. I went to local veterans services at my county. The agent helped me with the forms. One form was incomplete, fixed resent through vet svcs. They denied saying she has too much assets. Local guy said VA did it wrong. Applied again. Was in the decision phase for 6 mo. Told after so much time passed needed to update med expenses. Then told to update assets (which are going down. She will be on Medicaid in a few months). Now told no based on the orig form incomplete and the 2nd form also incomplete. And there is a discrepancy in assets now. I am in tears. My mother is 90.5. had heart attack in ALF last June. Been on hospice since. Her status puts her file in expedited status. I did everything they told me. I keep going back to local guy assuming he knows how to do this application. The only difference in assets is that they are going down having completely cashed out one account. We don't use my mom's money for anything but ALF and medical bills. She has no assets except IRA and investments. No property etc. My brother pays her bills and keeps track. It is a miracle she is still alive. She is down to 90lb. Advanced dementia. Doesn't hardly talk. Sorry I am so upset.
