The Hammers boss was convinced VAR Neil Swarbrick should have at least told on-field referee Chris Kavanagh to review the incident on the pitchside monitor.
But, speaking on Friday, Moyes refused to divulge whether he had received an apology from the PGMOL.
“I’ve spoken to Howard Webb and his team, but the conversation was private and it will remain that way,” he said.
Moyes believes there is more to come from West Ham’s record signing Lucas Paqueta.
Brazil midfielder Paqueta has scored in his last three matches, including a spectacular strike against Liverpool.
The 25-year-old had initially struggled to adapt to the Premier League following his £50million switch from Lyon.
But his recent performances have played a major part in West Ham climbing away from the relegation zone.
“I think he’s beginning to get used to the Premier League, because it takes time to settle,” said Moyes.
“I think he still has a bit to go, but I have to say, it is great he is getting some goals for us recently. It has helped us a lot.”
The Hammers head to Crystal Palace on Saturday to face another side who have enjoyed an upturn in results since 75-year-old Roy Hodgson returned as manager.
“I thought Roy was mad when he came back,” said Moyes, who turned 60 this week.
“But he has an incredible passion for the game. I can understand why people want to work with him because he is such a talented coach.
“I hope we can win the game – but I have to say, Roy has done a fantastic job.”
Gianluca Scamacca remains West Ham’s only injury absentee. The Italian striker recently underwent knee surgery which has probably ended his season.
“In the main we are OK,” said Moyes. “Scamacca is the one player who is not available. People have picked up some knocks in midweek but, hopefully, it will be a similar squad.”
