Wycombe sealed their win with a disputed late penalty after the Millers had battled back to 3-3 and Moore was far from happy.
He said after the game to the press: "We cannot get away with defending like we did in the first half, that is when the game got away from us.
"We got a bad decision with the penalty. The linesman said he didn't think it was a penalty and he was in a better position than the referee but he didn't agree and has given the penalty. I have had a chat with the referee but he isn't going to change his mind and it is done now.
"Johnny Mullins shouldn't have gone to ground in the first place and give him the opportunity. He did make a clean tackle, our 'keeper swears blind that it wasn't a penalty and I didn't think it was either.
"At 2-2 we missed a tremendous chance, then we have a lad off injured and concede a third with 10 men.
"Alfie then scores the penalty and then their 'keeper makes a world class save to keep out Jason Taylor. We had a chance when we got in behind them but instead of pulling it back Mullins hits it straight into the 'keeper's hands."
