Wolves lost 3-2, with three penalties given on the night, including a 94th minute winner converted by Willian.
Kilman told the club's website: "We deserved to get something from the game. When we equalised, we wanted to go on and win the game. But there are some factors we can't control, and we have suffered again today.
“In the second half we started to lift the tempo, but some decisions shouldn't have been given against us, so it's tough to take.
“I think the first penalty, they should not have got that penalty. I think it wasn't a foul. Our player [Semedo] got to the ball first.
“Our penalty that we won, the player was on a yellow card, he fouls him [Hwang], he's last man, he should be sent off.
“The incident with me, I've been headbutted and been too honest and not gone down, but it's not my fault.
“I didn't see the second [Fulham penalty] properly but some decisions are not going our and we're not getting any help from referees to see what's going on."
