After receiving 2 calls and no messages, I called back. BTW, I have a blocked number but apparently using a pre-paid calling card, it showed my phone number to the called Party. A not of caution if you want to remain anonymous.  Called Party ends representing RCI, the vacation resort company. They are trying to locate people with RCI Timeshares to alert them that RCI and or Resorts are changing policies and administration. The Called party did not try to sell me anything nor up sell me.  He offered to take my name off their calling list. Will see if he follows thru.
