Manager David Moyes felt his West Ham side were owed an apology after being "disrespected" by not being awarded a late penalty against Liverpool.
The Hammers lost 2-1 on Wednesday but Moyes was angry a spot-kick was not given after Thiago's arm hit the ball.
Referee Chris Kavanagh did not give a penalty and video assistant referee Neil Swarbrick did not tell him to review the incident on a monitor.
"VAR, for me, showed no respect whatsoever to us," said Moyes.
"You'll probably hear them coming out with some rubbish about he [Thiago] needed to break his fall, but if you lunge, it's your own fault for lunging and being out of control in the tackle.
