Claimed to be from some research group doing a survey on health and that my number was randomly selected. Yeah right - by their robocaller. Did not reveal any personal information and likely scammers.
I didn't answer, but a message was left by a woman who identified herself as Yvonne Torres of Professional Research Consultants. She added that she was doing research polling on local health care needs on behalf of Mission Hospital, which I knew to be a well-regarded health care provider in Orange County. The message said she would perhaps call again, but if she does she won't get through because I have blocked the number. There is a company by that name headquartered in Omaha, so this might be a legitimate survey on health care. Then again, the asserted PRC connection might be fake.
