yeah, I've been having problems with that as well. It takes about 6 hours after the matches finished to find out the score...
I normally just send them an email on their main website to tell them to 'please update the results for today's matches'...
Or you can just wait until someone on the WTA forums to come up with the scores. Don't rely on the bookies, they won't give a shit unless for sure who they're paying on, so it'll take longest with the bookies...
