Resort Travelers Inernational Ripped me off of rental fee's of $2400 Lake Mary Florida

I was contacted in April 2016 from a voicemail asking me if I wanted to rent out my Timeshare.  I was interested because I had owned this for over 10 years and I have never made a dime.  So I contacted Resort Travelers and the talked me into a one year or a three year contract to rent my timeshare.  The cost for one year was $1800 and for three years was $2400 so it made more scense to pay for the three year contract.  I signed up and paided $2400.00 for the three year contract that they would rent my timeshare and they said i should get an offer within 180 days.  It has been over a year and I have not recieved one offer.  They don't update me on anything.  It would be nice to get a call and let me know what is going on with renting my timeshare.  This is the biggest Scam.  Stay away from Resort Travelers they take your money and then you never hear from them again.  Like I said it has been over a year and I have had no contact.  My wife call them the Monday before the fourth of July and no one was there to take a call.  Really I would think that people that are last minute looking for a place to stay might call the place.  I still have not heard a word from anyone at Resort Travelers.  I don't even know what an offer looks like.  Stay away!
