I would think the biggest complaint we hear would be the standard Veterans Affairs Canada, “No, that's not good enough. Try again”.
I can tell you right now, one of the claims I put in, a legitimate claim, was being in war. I'm not lying to them, but they're calling me a liar. It really hurts. Then I had to go back. For one of my claims, I had to go to a hospital 10 times. The first time they called me and said they sent the paperwork to me. In the letter, they said they would send it to the doctor. I called a couple months later and they said I was supposed to bring it to the doctor. I said I was going to scan them a letter and send it to them right away. I did that and she apologized. She sent it to the doctor. They ended up losing the paperwork anyway. This claim has been going on forever. It's still not dealt with.
These are the situations that veterans get into, and they wonder why the veterans are so frustrated. You're leaving the military, losing your family, losing your job. You just lost 75% of your friends because you're not in there anymore, and now the one entity that is supposed to be looking after you is giving you the runaround. That's where the frustration is.
