These are Timeshare Resale Outfits. They claim to have a buyer interested in your timeshare. Some have actually gone as far to tell me, "I already have a downpayment from an approved buyer" These Shysters want you to pay up frount to clear & transfer title. The problem is they claim it takes 2-3 weeks to do title work, they then claim to give the supposed buyer 30 days to accept offer. By now 6-7 weeks have passed, they have your money, you have nothing, and because of the length of time from Credit Card transaction and you realizing you have been a victim, it makes it more difficult to recover your money. DO NOY PAY ANY $ UP FROUNT
