Grand Mayan, Grupo Mayan lied to, scammed, Internet

Like everybody else that took a vacation to Mexico, Playa del Carmen, Grand Mayan resorts. Beautiful there, said we were not going to buy another resort, but was lied to, stating we can sell our existing 3 timeshares, so we would not have to deal with the maintenance fees, because they had none, (that was the selling point for my husband). Only pay when you use. Lie, got a bill for annual maintenance fee for $1021. Other fees that I paid, that had nothing to do with Grand Mayan (I found out later), and got most of it back from my charge card. (Still working on more). Trying to get down payment and other fees I paid to transfer our old timeshares, which they said would cost around $200 to transfer all our existing timeshares, lied, they charged $545. for each. They also had the nerve to try to sell us back our timeshares, then later, oh "you can have them back at no cost".....My friends also bought into this and having the same problems. We charged $5915. to our credit card (which I am trying to get back,but was told I have to send the entire contract of all the paperwork from Grand Mayan), what a hassel!Our daughter paid $1500. cash, and my husband paid the rest off, $20,000 with a loan from his company stocks. What can we do about this? Help!!! We want our money back.
