A company out of Denver, Co. named Timeshare Rescue ripped me off. They have since filed for bankruptcy. But anyone who owns a timeshare should be made aware of almost any company who offers to buy your timeshare, the majority of them are a scam.
They either promise to advertise your timeshare for sale for a prepaid fee and it never sells, or want you to pay them a ridiculous price to take it off your hands. In either case, don't fall for fall prey to them.
The best solution is to contact an expert who you can trust to advise you what to do. There are solutions, but in many cases you will not like what you hear. There so so many who have bought timeshares and used them, but when it comes time to get rid of them, the fine print in the sales contract comes back to *** them bad.
