I would appreciate some opinions on courses of action. I received the brown envelop on Oct 12 on a claim submitted in July 2010. I was awared TDIU and my rating increased from 80% to 90%. The letter explained the withhold for the DFAS audit. Called DFAS and was told that they had done the audit and forwarded it to the VA in January 13. In Mar of 13, saw in the ebenefits that there was an administrative review that decreased one of my SCs from 20 to 10 without changing my overall rating and I received the corresponding letter stating that as a fact. I have been waiting for the retro and the DAV keeps telling me that I am in line. In April, the ebenefits posted an authorization review and said that a decision letter was sent and that appeal was possible. Nothing in the mail at all so far. Still waiting for retro pay. Any suggestions? Thanks.
