Who called from 5122765478

The name "John Gonzalez" shows up on incoming call.  They've been told multiple times to stop calling, but too stupid to understand.

Got a call from this number stating that they are trying to collect a debt.  When I told them i never received a letter, they gave me an old address that they supposedly sent the letter to.  After telling them I hadn't lived there in years, I realized I may have been saying too much and told them to not call me again.  I do not have any outstanding bills that I'm aware of...sounds like  a scam, especially when the number comes back to a John Gonzales via a google search

Every now & then I get a call from this number.  Of course, I don't answer.  But when I call back, it doesn't ring & says "thank you for calling.  Goodbye."  I know I shouldn't have called back, but, I was curious.  Now this is getting very strange.

CREDIT MANAGEMENT.  i ADVISED THE REP WE ARE NOT ALLOWED PERSONAL CALLS AT WORK.

This phone number links to a residential address in Austin. I'm not sure if the number is spoofed or if the person is really bad at defrauding people.
