Problem with Bodog deposit bonus (sportsbook)

[lotus guardian]

I made a $5k deposit on bodog about 2 months ago and their T&C's clearly stated that it was 1x B+D. They even told me on an e-mail that I had to wager $5500 to release the bonus. Now that I'm almost done they tell me that it's a 3x B+D and that support made a mistake before, even though I had read the T&C's.

I didn't know that bodog was so shady, I'm regretting having made a deposit with them. Does anyone know if there's something I can do about this?
