Don't know anyone in "Arcadia CA" so clicked "Talk" then "End" in succession to hang up on them, and then blocked the number and reported it to the FTC (not that it does any good).
Only one other report on this number (from 12/16/14) so must be a new scammer starting their rounds...
Called twice and left no message. Arcadia CA on our caller ID. Called again yesterday and left a message saying they would be at the house sometime today between noon and 5 have a photo ID. Supposedly someone used our name as a reference. They did leave a 844 number.
I called them back from a different phone, and the lady identified them as United Customer Information Bureau. I guess they're trying to make themselves sound official.
