Who called from 7135880921

Marvin, you received a court summons??? Is this place legit?

Just got a call from this number didn't answer and they did not leave a message so it must not be important

This is National Debt Collectors.  They call my wife regularly.  She hangs up.  I call them back and they either refuse to talk to me or leave me on hold.  Complete losers.  She blocks their number but they call back with a different number.  They should be put out of their misery.

They called my work number over and over, no message.
