Let me tell you how to handle the VA. I had problems with the IRS when they cleaned out my business bank account for not paying withholding taxes for my employes...I paid the taxes ahead of time and had the receipt from the bank. I had problems with Social Security when they had my birthdate wrong. I had problems with the IRS again over a form they said they throw away...but they really don't throw them away.
All three times, I walked into my congressman's office and filed a written complaint regarding the IRS...twice, and Social Security. All three times I got positive results. The IRS refunded my money including interest, they magically found the form, and Social Security changed my birthdate.
Here is my advice, take it or leave it. Notify the VA that you are going to contact your congressman's office. That alone might get things going. Next, walk into your congressman's office and file a complaint. Don't call, don't email...go in there in person. Have all of your facts documented as best as you can including names, dates, places, etc.
The employees there are non political. They will help you...not saying it will work out for you, but the people I have worked with really got my issues solved. They will go out of their way for former members of the military. I am assuming that you are eligible for VA treatment. The first step in climbing a mountain is taking the first step. Get moving.
