Don't understand this scam. Told me they were with RCI, and interested in buying our timeshare (which had been up for sale.) Called the following day, saying they sent me an email (which they already had my email address) with info. and numbers for me to call to receive an appraisal after gong online to listen to some webinart!!! No email, and the phone number they called from (865 868-2900) is permanently busy!
