Penn Credit sent letter for a traffic violation - Harrisburg Pennsylvania

It says that they are a collection agency that has been trying to get into contact with me for a traffic violation in Florida from 2007.Letter looks legit but there were a few clues to this being a scam.

 First,  the name on the letter was wrong. Had a guys name on it with my last name spelled wrong. Secondly it was from 2007 and neither I nor my family were even in Florida during that time (we live in the Midwest.) And then when my mom called the number listed the man on the line said not to worry about it because the letter was forwarded to the wrong address. That doesn't even make any sense. My mom then preceded to question things and he gave up too quickly just saying it was a mistake. So to anyone who receives a letter from this company in the mail, please beware.
