We got a call from this number today at 11:32 am. The caller ID was HANSON MA. No voicemail message was left. When I called back (our number is hidden by default on outgoing calls), I heard a recording which said "Press 9 to be put on the do not call list." The number will be added to our call blocker.

Called  several times in the past few weeks..  Claims to be  " Home Security Center" wanting to update our security system.  Have asked several times to be removed from  their list.  Calling the # results in a busy signal or recording saying  the number is unavailable
