Richard Hill praised opponents Stourbridge after watching his Whitehawk side crash out of the FA Cup.
Luke Benbow scored twice for the Northern Premier League side in a 3-0 win over the Hawks to set up a home tie with Northampton Town in the Second Round.
Chris Lait had opened the scoring in the second half after the Hawks showed a big improvement in the first half in relation to recent showings.
Hill said: ”Stourbridge played really well tonight, and over the two games were better than us.
“Up until the first goal I felt we made it really difficult for them.
“But then a decision doesn’t go our way, and all of a sudden we are two goals down and chasing the game.
“I don’t want to complain about referees, but I felt there were inconsistencies in his performance tonight which did us no favours.
“There are two teams on the pitch who are equally entitled to decisions, and I felt we didn’t get the rub of the green at all tonight.”
An even first half saw the hosts come closest early on, with Adri Munoz pulling off a great save to keep out Chris Lait’s effort from point blank range after Leon Broadhurst’s ball in eventually dropped to the attacker.
However, the Hawks should have gone ahead twelve minutes in when Danny Mills did well to get on the end of Reece Connolly’s flick on, and after skipping past Matt Gould, the striker could only find the side netting from a tight angle.
Sergio Torres then saw his diving header go wide of the post as the Hawks showed a much improved display from that in recent matches, with Mills seeing his tame effort comfortably saved by the Stourbridge keeper before the break.
However, it was the hosts who went ahead in front of a 1,993-strong crowd at Amblecote. A mix up in the Hawks defence saw Broadhurst tee the ball up to Lait, who finished emphatically from inside the area.
And Stourbridge went on to double their lead after the hour. The Hawks will feel they should have had a foul in the build-up when Javier Favarel was bundled over, but play went on and Lait put through Benbow who slotted beyond Munoz.
And the Hawks’ misery was compounded further fourteen minutes from time. Not for the first time, a soft free-kick went the way of the hosts, and Benbow stepped up to curl into the bottom corner from 22 yards.
Hill’s side had chances late on to get on the scoresheet, with Ahmed Abdulla and then Mills both off target, but it proved to be another frustrating night for the Hawks.
The Hawks boss added: “Danny is an honest player, if he goes down when put through in the first half, maybe it’s a penalty, and the referee has a decision whether to send the keeper off.
“The lads feel aggrieved, as he had pulled play back on several occasions prior to that, but has said he couldn’t do so on that occasion.
“We now need to roll our sleeves up for a big month ahead, with several league games coming up.
“We need a response, and I am confident in the players that they will produce.”
