John Coleman says Accrington Stanley were robbed of three points after Gillingham were awarded a late penalty in a 1-1 draw.
With just six minutes remaining in Saturday's League Two clash at Priestfield, substitute Ian Craney put the visitors on course for their first away win of the season. But Gillingham equalised just moments later through Luke Rooney's spot-kick after Lewis Moult was adjudged to have fouled Danny Kedwell in the box.
Coleman said: "It's disappointing that we conceded straight from kick-off but on another day we get a foul on our player before the referee gives the penalty.
"But the referee's consistency went out of the window in the second half. It appeared that any foul for a push was going to go against Accrington.
"People have to remember how far we've come in a short space of time. A couple of years ago we came here and got absolutely murdered.
"We got beaten one-nil, but it was a thrashing. Yet in this game we've come here and we're going home disappointed because we feel we were equal, if not better than Gillingham. That shows how far we've come and how much the players believe in themselves."
