Wyndham resorts Sales scam, deceptive sales practice Nationwide

It is very hard to confess one's own stupidity but I hope that my report will help other people to avoid the fraud I've fallen into. I was stupid enough to buy certain amount of points from Wyndham resorts. The sales person who sold me those was stating that I can use these points for travelling needs like buying air tickets and car rentals and my invetments will be payed off in a few years. When I tried to use this option it popped up that the value of points I have, converted into money (price of ticket or rental) covering just 1/3 of maintenance fee that I have to pay every year. I called customer support trying to cancel the contract and get my money back. I was told that they don't do that and they recommend to call real estate agency that handles these transactions. Real estate agent told me that the price of my points is just 5% of what I paid a year ago.
