Steve Kittrick spoke following the 2-0 defeat to Shaw Lane in the Buildbase FA Trophy on Saturday.
The Boro boss was disappointed with the decision to send off Boro defender Jameel Ible.
He said: "I didn’t see what happened with Jameel when he got sent off, but I think referees have got to be consistent. We’re getting so many mixed messages, apparently they’ve both had a bit of a tussle.
"We had the same thing earlier this season with Benny, but we’ve seen loads of it going on and some referees give it and some don’t. Jameel said it was something of nothing but it's just being pedantic to me and its killed the game for us.
"From the free-kick they went and scored. I thought Jordan could have done better to get across and he’s admitted that in the changing rooms afterwards."
Kittrick thought his side improved after the break and praised the work rate of the Boro players in the second half.
"We got the lads in at half-time at 2-0 down and we had a go in the second half. I thought possession wise we were the better side and then when we went down to nine men we kept at it and you’ve got to admire the lads for putting a shift in.
"But we shouldn’t have been in that situation. I’ve said to both Jameel and Scott that it’s unprofessional; we’re down two players now for three games and that is just not acceptable.
"I thought our application was a lot better second half, we set off well despite losing 2-0 and we still had a go. Benny’s had a chance and Browny’s had a chance. Other days they go in but that's football."
The Boro boss felt his side brought the goals conceded upon themselves in the defeat.
"Fair play to Shaw Lane, they’ve got through but I didn’t see anything that really concerned me. They’ve beaten us 2-0 but I just think we had enough to test them 11 v 11. They haven’t hurt us when we were down to ten men or even at nine men, we’ve hurt ourselves. That’s killing me at the moment.
"They’ve got through and I hope they go on to do well because I know a lot of people down here."
Looking ahead to the home game against Hyde United next weekend, Kittrick took some positives from the way his side responded in the second half.
"We’ve got to bounce back and the positive thing to take out of this is the second-half performance. At 2-0 down at half-time me and Chris felt we had to get our message across in the right way and tell a few people to get a response and I think we got the best out of most of the team after the break. I think Scott’s sending off is just frustration, it was just a ridiculous tackle and means he’s now out for a few games to leave us short for next weekend."
