But what Optional is saying is that the cs representatives aren't sports bettors, so it doesn't really matter now many other books offer the bets, if it's not obvious how the wager should be graded to someone who doesn't do any sports betting, there is some potential confusion.
What doesn't make sense, of course, is for the book itself to be grading wagers that way. From what I can tell, in my experience anyway, this is just how certain wagers are actually graded. So, in terms of the person (or automated system) doing the grading, or cs, the wager is actually graded correctly. Hence why it's such a pain to deal with. (This particular case may be different, I don't know. But, for the experience I had, I saw another post several months later with exactly the same thing. On the opposite side of the wager. And the person, who was kind enough to point out that their wager should have been a loss, was equally unable to explain this to cs. So, if I happen to encounter that situation again, I would not be at all surprised if I have to go through the exact same hassle again). I've decided that I'm willing to put up with this, since I deal with any amount of crap with online sportsbooks anyway, but you would indeed think that a top rated sportsbook could actually fix stuff like this.
