Every week there's a topic like this. As I said in another forum, it gets old in these cases because the bettor is surprised that a site stupid enough to supposedly say over the phone that the odds were correct is not going to honor the bet - it's like petting a shark and bitching when you lose a hand.
Just assume, in the future, all such obviously fuc-ked up lines are not going to be honored and just avoid them. Save yourself the hassle. If they told you that on the phone, ask them for a playback, if you bet it over the phone - if not, live and learn.
