There's one lesson you should take away from this..

Run your own parser.

That way, you have evidence of what's really happening with the damage, instead of being forced to believe what someone else says.

There's one constant among the idiots that play this game and fail everything they try, they always try to blame someone else. It's up to you to protect yourself and know what's really going on. It saves a lot of time and stress, and gives you sufficient ammunition to remove problem players from your groups.
