Company alleged that I owed $ XXXX+ on a payday loan, despite the fact I have never received a payday loan. 
They were extremely aggressive and hostile on the phone and threatened to take legal action. 
They never disclosed the " mini-miranda '' or that this call was to collect a debt. 
They also called daily, sometimes multiple times, leaving messages each time they called. 
When I asked to receive debt verification, they claimed that they had already mailed documents previously, but I never received any such documents. They refused to send me any documentation or verification and only got more hostile on the phone. 
Most distressing was that they had personal information including name, address, bank information, and social security number. 
This was most definitely a debt collection scam.
