Don't bother UB. When i try to lay a longshot for a $500 liability I get asked if I will accept $200. I rang a rep of theirs who seems like a good bloke and asked him why they would refuse a bet when their liability was about $20 ( mine was 500 ) and he said it didn't seem right and that he would check and get back to me the following Monday. That was two weeks ago and I haven't heard a word.
On the positive side I won $600 during the trial and since and I had no trouble making my first withdrawal for that amount.
