Who called from 8067656346

I keep geting the same recorded message from three diffrent numbers out of Lubbuck Texas.  The recording say's my name and gives me a number to call back with a confirmation number given.  They are driving me nuts.  I called the number and it just rings and rings.

A recorded message says:

"this is an important call for John Smith  (my first and last name).  If this is John Smith, please press 1."  

Then I pressed 1 and the recorded voice says, "to confirm that you are John Smith, please enter the last four digits of your social security number."

Then I hung up.
