The home side recovered well to equalise twice in the second half.
Los Blancos manager Joel Minsky told JC Sport: "We feel today was a missed opportunity. UJIA are a very powerful team, and around the time they scored their first two goals we couldn't really get near them - although we feel we let ourselves down with some sloppy defending.
"For the majority of the game though, we had them on the back foot - they weren't able to deal with our short game. However, we weren't able to find a winner in the
closing stages.
"That's our BG campaign over with for the season, and it's very much been a question of 'what if?'.
"We snatched defeat from the jaws of victory against Glenthorne, put in a terrible shift against one of the Division Four's bottom teams, and were unable to break UJIA down as we chased what would have been a deserved winner today.
"Our performances against Glenthorne and UJIA were both superb, but to beat the top teams you need a bit of luck on your side too, of which we've had little.
"We're much better value than two points from three games shows."
