My phone rang, when I answered it the person hung up. I called back, I was immediately barraged with personal questions about my address, my birth date, etc. I repeatedly asked what kind of company they are, she avoided all my questions and became combative in her volume and questioning. I told her since she was not answering any of my questions and I am not in the habit of giving out personal information to anyone who calls I was going to hang up and did.
I then looked up the company on Google, found multiple rip off reports and can only conclude that this company buys what they perceive to be a good bet on old paid off debts that people may have forgotten about or have been paid already.
