Manager Geoff Butler branded the refereeing an "absolute disgrace" after Bashley were deprived of a late penalty in their 2-1 Ryman Division 1 defeat at Dorking.
"It looks like sour grapes, but it wasn't even a difficult one to give," he seethed. "Danny Gibbons was clean through and the defender was chasing the wrong side of him and just hacked him down.
"It was one of the most blatant penalties I've ever seen, but the referee was right on the spot and didn't give it and the linesman did nothing either.
"I feel totally let down by the officials. It was disgraceful. If they can sleep tonight, they've got no conscience."
Arguably Bash might have had two penalties. Earlier they had a strong shout waved away when a Dorking defender appeared to control the ball with his hand while down on all fours in the box.
"I spoke to the referee about that one at half-time and he was so superior and arrogant it was untrue," said Butler. "If players and officials are miles apart, that's why.
"That sort of attitude does nothing for relationships in the game.
"Admittedly there might have been an argument for the first penalty appeal being ball to hand, but the second one was clearcut. It's abysmal that we didn't get it."
With Team Bath defender Graham Mills making his first start for the club, Butler reverted to a flat back four and admitted: "We were all over the place to begin with."
Nusungu punished them with the opening goal for Dorking after seven minutes, but the Foresters settled and levelled four minutes later when Gibbons got across his marker to meet Dave Wakefield's corner.
Richard Gillespie had chances to add to Bashley's tally, but Nusungu grabbed a 63rd-minute winner.
"We played some nice football and deserved a point," said Butler. "Gilly had a good header in the first half and another when he came off the back post from a corner and the ball hit a fella on the line.
"In the second half he should have sidefooted one past the keeper, but he slashed at it and put it wide.
"Full marks to Gilly, though, for getting into so many good positions."
Defeat drops Bash down to sixth place ahead of tomorrow's tough home test against lofty Metropolitan Police.
Newport IoW manager John Linington is feeling far happier with life even - though his side surrendered an early two-goal lead in a 2-2 draw at high-riding Bromley.
He is convinced that the signing of ex-Eastleigh striker Dave Greening - son of legendary Island hotshot Steve - could transform Port's season.
Greening took only two minutes to score following his move from Brading Town and, three minutes later, Adam Barsdell made it two.
But in an incident-packed match, both teams missed penalties - Joe McCormack saving a Bromley spot-kick controversially awarded for handball by Justin Hughes and Barsdell squandering Newport's chance after Greening had been pulled down.
Although Bromley clawed back with goals from Huggins and Watson, Linington was chuffed with his third-to-bottom side.
He smiled: "Dave Greening and Barny (Barsdell) were out of this world against a very strong Bromley team. Greening was red-hot and worked really hard. To say he'll make a difference to us is an understatement! He's given up an easy life at Brading to play for us. It's a shame a few others on the Island won't follow suit."
Port also benefited from the return of ex-Gosport midfielder Kev Youngs from a long-term calf injury.
A hat-trick from Lee Paul secured Fleet Town their first home win at the 3-2 expense of Cray Wanderers.
The 22-year-old former Havant & Waterlooville marksman bounced back from injury in sparkling form as Cray struggled to contain him and strike partner Richard Mealey.
Shaun Hale created Paul's first two goals, which were sandwiched around one from Ross Lover for the visitors. With nine minutes to go, Paul tapped in a rebound to make it 3-1 before David Gray headed a late reply.
