One thing I'm noticing about SIA is that they grade bets wrongfully on a pretty regular basis. You have to contact them to get it all fixed, which might be a problem if you have a couple of futures pending that will get graded in two years' time. Since you can only see your graded bet history for the last couple of months or less, once those futures get graded you will never see them in your history (they are chronologically sorted by bet date, not event date or grading time). So if there is a problem and you make a lot of bets regularly and thus not notice every little balance change that occurs or simply forget that you have a couple of more bets that are very old, it's possible that you will never discover that they ripped you off.
This incorrect grading thing happens a lot. To me, more often than at all other books where I play combined. Of course, they never mistakenly grade in your favour.
This one is my favourite to date: last year they voided my tennis winner (Jarmila Groth) citing wrong player listed (listed player was, you guessed it: Jarmila Gajdosova
)
Oh yeah, and they limit really fast, to a couple of bucks - even if you have a rollover to meet. I think SBR should have a rule:
a book that limits players before a rollover requirement is met cannot be rated B- or higher. Because some people have better things to do than make 3000 $1 bets to withdraw money that is theirs, which the book is merely holding for them.
Also, maybe it's different now, but a while ago if you had an active rollover and decided to make another deposit, you could NOT withdraw even a penny of your second deposit (that had no bonus and no rollover, had virtually nothing to do with your first deposit) until satisfying your original rollover requirement.
