Have received hundreds of calls from this number tried on several occasions to contact the caller the machine that answers wants a code number that I have never received dead end. Finally put this number on the block call list, still they call dozens of times a day now it just drains my battery because my stupid phone still registers the call as a missed call and burns battery . My next step is to contact my phone company and probably change my number to get away from this company and their ruthless tactics. for anyone who cares the number is 415-894-5944 company unknown.
