This company has called me many times trying to get me to attend a timeshare presentation in Las Vegas. I always tell them no and to take my name off their calling list. They use various numbers to call me so I cannot block their number. The most recent time, June 5, 2018, they used the "Can you hear me?" scam to try to get me to say yes. I immediately hung up. I have no desire to attend a timeshare presentation and am not desperate enough to fall for the free vacation pitch. I have a timeshare through a different company, Diamond Resorts, and wish I never purchased it. Diamond Resorts does not use RCI for their vacation exchange (they use Interval) and I have no idea how I got on RCI's calling list.
