Auto Loan Network unethical, harrassment, insult Providence Rhode Island

This company has called me repeatedly (12 times today alone) looking for a person I don't know, but they refuse to accept that I don't know this person.  I was told I would be called for as long as it takes for them to get paid, whether I knew this person or not.  One of them called me and called me a "Mother F*****  (over 30 times in a 5 minute conversation) and told me to quit calling them and complaining (which I ignored).  

They have used at least 10 different phone  numbers from at least 3 states, including Rhode Island, Texas, and Florida.  

I have filed a complaint with the FTC.
