I, too, received a call from these idiots, and my Caller ID said IMRAN KHAN CANC. Other posts indicated Caller ID's saying UNITED VOICEMAIL. One post said the caller talked about the old "Federation of Police" scam. One posts indicates this number is a legitimate number for a cancer hospital, but let us remember that these scammers often "spoof" legitimate phone numbers. This is clearly a scam to me, and they are blocked!!!!!
