I recently listed a car on craigslist... I will almost 100% guarantee this is related to that. These fu*kers take the massive amounts of data we ourselves give to them daily via the internet and our smartphone apps and they use it against us. They're the feces of scum suckers. They have never done anything meaningful for the human race and they should pray I never encounter one of them.
I also got a call today from this number, and there was a recording saying the name of the company and blah blah and that is ia collectors agency, and to call them back and more blah blah, and it was in plain English not Spanish. It was recorded on my answering machine but I just erased the message. Whoever they are, STOP bothering me or I will have to block that number.
