I answered and they said they are from Wakefield and Associates Collection Agency.

They are a collection agency.

These people have been told several times that I am NOT the one they are looking for.  They continue to call.  I have the phone number blocked on my phone, but it's still a pain to see it come up on blocked calls.   I have no choice but to get an attorney to do a  cease and desist letter, maybe get a $1000 settlement for harassment -  these people won't quit.
