I did file a complaint through the phone system, and they sent me a letter stating that it was sent in September. Went into the VARO yesterday, and they said that there is a statement saying it was sent, but they cannot pull up a copy (which apparently they should be able to).
You stated "Click on the Contact us button and they will direct you to the Iris site." However, when I look on the site you posted, Clicking on the Contact us button only gave me numbers, no reference to IRIS.
I spoke with the POA and he said he doesnt have it, and is going to check with a warehouse where it could have been sent.
I did confirm the address via all four (POA, VA Phone System, VA Hospital and the VARO)
Funny thing is I have one of my old C-Files (2004) and may have found a CUE I disregarded a few years ago related to a separate issue (Migraines), for some reason when they did my C&P, the doctor noted that it began during my time in service, however, and this is really odd, she stated that it is Not at least as likely Not related to Tinnitus. yes double negative, and I have no clue why she was making a statement in relation to Tinnitus. When they denied it, they stated not related to military service, and that was that. But that is a query for another post.
I was far more concerned with the Hearing, Tinnitus, and Ear Disease (later dx'd as Menieres), and did not really pay much attention to it. My first claim was more of a blanket claim to ensure military issues were identified. I thought it odd, but it was a recommendation my VSO, while I was still in Florida, made at the time. It included a 0% SC I received for a scar from a surgery, 0% for hearing loss (I can understand words when the volume is turned up enough), 10% (eventually) for Tinnitus, non-SC for an injury to left Hip, non-SC for Migraines among a couple of others, I cant recall.
