Well, I'm glad I searched this number online and found your post.  This number has called me several times and left threatening messages concerning a legal matter that arrived on the desk of "Attorney Mason"  I was so confused so I decided to do some research online for anything I can find.  Thanks for your comment.  Now I know how to handle this guy when he calls me back

He's also calling from,(210)802-4534. And (210)598-8642.

Under the Federal FAIR DEBT COLLECTION PRACTICES ACT

False statements. Debt collectors may not lie when they are trying to collect a debt. For example, they may not:
   falsely claim that they are attorneys or government representatives;
   falsely claim that you have committed a crime;
   falsely represent that they operate or work for a credit reporting company;
   misrepresent the amount you owe;
   indicate that papers they send you are legal forms if they aren't; or
   indicate that papers they send to you aren't legal forms if they are.

Debt collectors also are prohibited from saying that:
   you will be arrested if you don’t pay your debt;
   they’ll seize, garnish, attach, or sell your property or wages unless they are permitted by law to take the action and intend to do so.

You cannot be arrested for ordinary civil debt.  Being in debt is not a crime.  These people are in violation of the law.  

Report them:

Also contact your local attorney general

If they continue to bother you, tell them that you know this is  a debt scam and that you are making a complaint to the police for extortion.  Once you get a copy of the police report and they call you again , just read out the  file number and the name of the PD or Sheriff’s office involved.   Tell them you’ll be glad to send a copy to them at whatever address the jack***es are working out of now.  If you can find them.
