The caller claimed to be from UPS dispatch with an undeliverable medical package for my relative. Was trying to get the name and address of the rehab facility where my relative is being treated. No medical equipment had been ordered. He didn't have a tracking number. I checked with UPS and they did not recognize the dispatch number. He had my name, my telephone number, and my relative's name and home address. He was fishing for info! Possibly a real estate private detective? Or worse.
