unitab stuff up again

unitab tonight had the treble on races 3,4,5 at the vaal in south africa where as sky racings first event to be broadcast (as advertised on the website) was race 4, now the winner of race 3 'just a spark' was almost 40/1 on the south african tote & is showing $4.30 (fav) on unitab so it looks like some smarties have got on after the race seeing they have got the times/races incorrect, unitab are not showing any dividends for both race 3 & 4 atm........so what happens with this as i'm not sure of the rules regarding something like this, i could only presume bets taken after race 3 had actually started would be cancelled & all other bets to be alive but as i said i do not know the rules......surely someone at unitab will have to accept responsibility for this MALfunction
