Unitab Rip me off again

How can this happen.....
I have had $100 all up Robert Thompson into Lovelock-Wiggins and $100 and Robert Thompson into Jeff Penza in the two JC's today. $200 outlay
Thompson has saluted at $1.90 with ease and I had the other two going at $8 which I thought was overs.
3 minutes before the last race they abandon the last race and call off the JC
when Lovelock-Wiggins is on 7pts and could only be beat by Angland on 6pts. Lovelock is on a 10-1 pop and Ang is on a 26-1 pop in the last.
FFS. I was of the understanding if 5 races were conducted the JC stood. Can someone find out coz this has pissed me off and cost me big time......
