Wolves skipper Conor Coady insists referees and players still remain baffled by VAR.
Nuno Espirito Santo's side were held to a goalless draw by 10-man Leicester on Friday after Willy Boly's goal was disallowed.
The defender's first-half header was chalked off after a video review showed Pedro Neto's ankle was offside in the build-up.
It was the second time this season Wolves had seen a goal ruled out by VAR against Leicester after Leander Dendoncker's strike in the 0-0 draw on the opening day of the season was also disallowed.
"I don't think the referees know what's going on and we don't know what's going on," said Coady.
"We should have won the game, it's as simple as that, but we don't understand the decision, I don't think many people understand the decision, but it's been made and that's twice against Leicester now this season.
"We felt it was cruel at their place as well. I don't want to speak about VAR too much. I've spoken about it before and it doesn't really get you anywhere."
Wolves, who sit seventh in the Premier League, still could have won after Hamza Choudhury was sent off 14 minutes from time for receiving a second yellow card, with Raul Jimenez heading wide and Kasper Schmeichel denying Adama Traore.
"They're a fantastic team. They've done brilliantly all season, have a brilliant manager and brilliant players," Coady told the club's official website.
"It wasn't the fact they were down to 10 men, it was the fact that we kept on going, we kept on playing how we want to and showed our character."
"So nobody knows!?" 🤷♂️

Espirito Santo questioned another controversial VAR call against Wolves after their 0-0 draw with Leicester.
Willy Boly's first-half header was disallowed after a video review ruled Pedro Neto was millimetres offside in the build up.
Hamza Choudhury was sent off for the Foxes after picking up a second yellow card for a reckless challenge on Leander Dendoncker with 14 minutes left.
But Wolves were left frustrated and only Sheffield United, with five, have had more goals ruled out by VAR decisions in the Premier League this term.
Nuno said: "There used to be an expression here in England about 'clear daylight.' in these decisions.
"The law is the law, but is there a clear advantage? I'm still positive, I'm upset of course because Molineux was buzzing and suddenly was down.
"Something has to be done. When you have something and someone takes it away, you don't like it but the law is the law.
"I'm not a specialist on refereeing, we are not judging the work of the referees here. I'm frustrated with the situation and all that is involved. We should not be sitting here talking about this."
The point lifted Wolves to seventh in the Premier League, three points behind fifth-placed Sheffield United, with fifth now possibly offering a Champions League spot after Manchester City's two-year European ban for breaching Financial Fair Play regulations.
Nuno played down the race for fifth, though, saying: "You think we are chasing something? We chase a good moment to recover and Sunday we are going to start preparing for Thursday (in the Europa League against Espanyol).
"We don't think about anything else. Thursday is going to be very tough."
Laura Woods talks Nuno Espirito Santo, and how the way he dealt with a technical problem reflects the way he is quietly doing incredible things at Wolves.
