I get calls on my cell phone from "An exclusive offer from Marriott...." I hang up and block the call. When I called back, I heard office noise in the background, but no one talking. The same introduction has come from the numbers 408-666-9181, 408-666-9624, 408-666-4047, and 408-666-9572 (Probably spoofed). Apparently a robocaller. Next time I'll listen to the whole pitch.
