Burnley manager Eddie Howe was left fuming after struggling Millwall snatched a 2-2 draw in a bad-tempered match at Turf Moor.
The visitors scored very early and very late to avoid their fourth consecutive defeat and lift themselves out of the relegation zone.
But Howe was less than impressed with the performance of the officials - who turned down two penalty appeals from the hosts and then struggled to maintain control as tempers boiled over in the second half.
And referee Craig Pawson was booed off the pitch by home supporters, with Howe particularly angered by the drawn-out decision to disallow Junior Stanislas' second half strike for offside.
"I've not had an explanation from anyone yet. It was a bitter blow for us because I thought we were 3-1 up for a long time and the crowd did as well," he said.
"I have never seen a decision like that in football before in all my life. It was very, very cruel on us because you think that with a two goal cushion it is game over.
"We then had to play the rest of the game out with just one goal in it and it was a psychological blow for us.
"I felt we also had two blatant penalties turned down so you can see why I'm not too happy.
"We had chances to probably win two or three games and it was a shame that we went in only one goal up because I felt we deserved more."
Liam Trotter eased the pressure on under-fire Lions boss Kenny Jackett, scoring from the edge of the area after just three minutes.
But Ben Mee restored parity with a close-range header while Charlie Austin gave Burnley the lead in the 43rd minute with a brilliant header from the edge of the area after Kieran Trippier's cross.
Stanislas had a goal chalked off for offside, although only after a long discussion between Pawson and his assistant, a decision the hosts were to regret as Millwall levelled two minutes into stoppage time when Darius Henderson netted from the edge of the area.
Jackett was certainly a relieved man and said: "We showed terrific spirit and we could have won it right at the death.
"When you have lost three games on the trot, you need a draw to stop the rot and the players should take confidence from that second half.
"If we can eradicate the goals against we are certainly competitive and have players who can score. We have two of the three things needed to win on a regular basis.
"We just have to keep working away at it but I felt in the second half it was an excellent performance and we thoroughly deserved the result. We dominated the second half and created a high number of chances."
And Jackett insisted the referee got it right with his controversial offside decision.
"I think it was definitely the right decision," he added.
"I couldn't believe the referee was going to give it. Martin Paterson was clearly offside."
