That's probably not a bad outcome for you, and it's also an illustration of why it's generally best to not bet obvious error lines like that.
Best case you get your bet refunded - there's no upside for you, and your money has been tied up for some period of time. Worst case they freeroll you - they keep your money until after the market has been settled, grade it as a loser if the Pats somehow win, and just refund you if they don't citing the obvious error in the line.
