Buck, I'll start with the last question first...I'm fairly happy more content.
Did WWP treat you like a disabled veteran? & explain the claims process ? Yes, they refer me as alumni and offer benefits above and beyond most orgs...I think. I believe the claims process is similar to the rest. They spent a great deal of time pouring over my record, deciphering the handwriting and offering suggestions. The well known org that I went with first wouldn't even return my communications...and I was a member for 40 years.
Did they file all your correct forms and tell you the reasons why? Yes, they filed correctly and explained their logic.
Did they charge you for any service they did for you? or and % from your awards? Absolutely free of charge
Did they keep you informed of any changes during your claims process? before they actually filed.? Yes and yes
Like any of these orgs, the more that you can help them the better the input. If you are putting everything in their hands and not willing to be involved in research and all aspects, you will be disappointed with the results. They encouraged my input, research and logic.
The biggest advantage is that they see more than I can. They can actually see when the next milestone is. There is an actual date that the VSR or rater is going to dust off your claim. This is probably why communications are sometimes spotty with the VSO. That said, I'm painting with broad strokes. It's still like being a student in a class of 100 instead of 5.
I get more info here and I use it to press my WWP rep. "The squeaky wheel gets the grease" when it's respectfully squeaky.
