Sundance Vacation Scam help....?

Question

I got talked into purchasing a $1000 membership with sundance and now that I've read some testimonials I regret having bought it.... They didn't even tell me on the phone that they would be trying to talk me into buying something but anyway,....after 3 hours of hardcore persuasion from their part they finally got me to agree they lowered their price from 1500 to 1000 which at the time sounded like an amazing deal..... I paid on credit card it did how ever say no cancel and no return..... do you think I would by any chance be able to get my money back.....
