REALTY TRADE SCAMED ME OUT OF MONEY/LIED TO ME ORLANDO, Florida

I was promised to sell my timeshare within 2-3 weeks based on the week, price and location @ Orange Lakes River Island.  I was told he already had offers on my unit but could not advertise it until the 895.00 was paid upfront.  I paid him in full and called and e-mailed numerous times but no response.  After 8 months I asked for refund as promised and was told they would give me another 6 months free.  I refused but that is what their perception was and was hung up on.  I called back and spoke to management and was told no refund could be given because I agreed to another "FREE" 6 months.  That time has passed and still no answer.  I have called the last couple of months just to find out the toll free number has been disconnected.  I just want my money back and I hate to think that it was a scam to purchase the unit to start with and a bigger scam to try and sell it...............
