For the past six to eight months I've received an automated voicemail from this number looking for Kerwin L. Williams.   I don't know anyone by that name and no one by that name has ever lived at this address.  The recording identifies them as a debt collector for the offices of Gordon Armstrong.  I've called them twice and confirmed I am not this person.    I'm already on the no-call list but evidently their offices don't review this list.

Same here, all I can do is just block their number.

it is Gordon Armstrong and usually is a matter of medical debt

I received this call and immediately blocked the number. I remember getting calls from the same caller in the past. They called quite frequently at the time. Now they are blocked.
