Any Wyndham club owners please help!!

For the past couple years, we have went to the Wyndham presentation to get the free vacations. Every year we said no… until this year. Everything they told us was a lie and of course they made it sound great with all of these perks to get us to sign up. We told them we did not have the money for the payment and they told us we could pay $75 a month. We signed up, they opened us each of our credit card and said we could use it to build points on every day purchases and then that would basically pay off the monthly maintenance fee. After we left, we realize that they are putting the $400 payment on the credit card that has 30% interest! When I called my sales people freaking out they told me I could sell my points to Wyndham for $5000 per hundred thousand points. Fine with me I will sell my points for this year, the bonus points they gave me, and the points from next year and get out from under this debt, right? Strung me along for two months now they say I can’t do that and they can’t help me post them that I have to learn how to do it and post them myself, which I could’ve done two months ago. We have worked so hard to build our credit and our lives from the ground up and now this is literally going to ruin our lives. I have the whole closing recorded. Has anyone gotten out of this other than not paying and ruining their credit, or paying, and then letting them take it back?? Any advice on anything is greatly appreciated!!!
