I called the number back an answering machine picked up first then I pressed 0 and the person that answered said he was part of a legal firm with Nelson Hurst and A**. I asked what is this about and he said I needed to pay on a debt I owed from 2003. Man that is a long time ago. I looked up the number on line and it is located in Harris, Texas. He also claimed that the office was in Georgia. I wonder what he is doing calling me from a 713 number rather than a number from Georgia. I think there is something funny here.
Collection agencies will sometimes use a local phone number even if their office is located in another area code. The try to get you to answer the phone, because most people will not answer the phone if the call is from an unusual area code. I'm not sure how the phone system is set up, but they route the phone call through a local number.
I called the number back and its says Nelson Hurst and Associates
