Bedfont had two men sent off and shipped six goals at home to Banstead Athletic on Tuesday night.
They were hit for six by a team they beat on penalties in the cup only two weeks ago, on their return to Combined Counties Premier action.
But the Orchardmen, who were 3-0 down at half-time,were not helped by some appalling refereeing by Andy Roberts after the break. He sent Tim Pitt packing for back-chatting, then gave a penalty and sent off James White after he cleanly won the ball in the box.
The spot-kick made it 4-0, then Banstead ran in two more to make it 6-0 when Bedfont were reduced to eight men after Lee Gritt left the pitch injured, with all the subs used.
Pitt's red card came following his return to the club from Ryman League side Northwood, who he left for a few weeks back.
Bedfont have the chance to put things right when they host Sandhurst on Saturday before making the short trip to Egham on Tuesday. Tuesday night's other action saw Feltham crash out of the Southern Combination Cup, going down 3-1 at Sandhurst Town.
But Hanworth Villa's Division One Challenge Cup tie at Dorking was called off due to a waterlogged pitch.
Villa return to Combined Counties One action following a three-week break when they host South Park on Saturday, then Knaphill in the Southern Combination Cup on Tuesday.
