Received call 4/19 at 12:44 p.m. Mountain Time. Caller Id said "Orlando FL."  I don't know anyone in Orlando so didn't answer. Caller left this voice mail message:
"Hello my name is Rachel I'm calling in regards to your Blue Green and RCI membership. I had a few questions regarding your account. Please give me a call back at 321-251-3741. Thank you."
I googled "RCI Membership" and results show that RCI is a timeshare company. I blocked the number and reported the call to Do Not Call List website.
