Looks to me like both parties are at fault, but mainly Bluegrass.
As a sidenote, I'm not aware of ANY book that takes 10 dimes on a soccer total in ANY league. Soccer totals are EXTREMELY soft, and the books know it. You can get down 250k on an asian side easier than 25k on a soccer total.
Bluegrass would be in its rights to cancel the excess wagers before the game began. If most of the wagers were placed at least 2 hours before gametime, Bluegrass had a fair chance to treat things fairly. Sportbooks know what their position is on any game long before it starts. If there was a huge imbalance (i.e. 10k on a weak soccer total line) and they didn't cancel the bet before the game began, two things are certain: 1. Bluegrass was aware of it; and 2. Bluegrass took a shot at you.
The matter is made worse, since there was a history between Bluegrass and the player, permitting this type of wager in the past. If these types of wagers were allowed due to a "bug" in the software, Bluegrass could have 1. emailed the player, telling him this type of wagering is not allowed, or 2. suspended the account, which would definitely make MyfootballGame contact them, and then they could discuss the repeat wagers.
You should make your case to Sportsbookreview - if they agree that you've been screwed, a demotion of Bluegrass's rating there will hurt more than anything TheRx can do.
MyFootBallGame (and all players) - if you are able to place 2 consecutive limit bets at the same price, you're asking for trouble, even if the software allows it. SIA routinely screws people (and gets scoffed for it) when a player does this same thing. If you're not sure if you should do something, ask! Think how strong your case would be now if you had an email saying "MyFootballGame, thanks for asking. You are certainly allowed to bet the same game over and over, as long as you wait 60 seconds between each bet." Or, the book tells you "No, don't do that." You nod along, but are saved this kind of hassle.
When in doubt, ask in writing (email). Shady wagering option? Ask. Unclear bonus (whoring or pro)? Ask. Prop rules? Ask. Once you ask, and get a response by email, the book is stuck. They can't even wiggle or squirm - there is no saving face, except admit they're a stiff book. But in a situation like yours, you left it "in the grey", and you could have made it black and white.
