I have been getting calls from this number and other 415-422 numbers every few days around 7PM for over a month. Have not picked up and there is never a message.
I, too, have been getting calls from the (415) 422-xxxx numbers. They never leave a message.
(415) 422-5229 10/18/14
(415) 422-5396 11/08/14
(415) 422-5165 11/13/14
(415) 422-5390 11/22/14
(415) 422-3536 11/23/14
I recommend NEVER answering a call from an unknown number. Obviously some kind of scam going on with these numbers. Only a matter of time until they get busted.
