500FastCash fake loan or fraud? Internet

I've received multiple emails indicating that I have taken out a loan with this fraudulent company.  First thought it was spam, but continued emails had me concerned.  I called to report to the company, perhaps it's just a wrong email address.  First representative (Nita) insisted she needed the last 4 of my social, then my last name, then my email address, finally the name of my bank.  (Gee, any alarms going off here?)  Finally get through to a manager (Danielle) and she expects that I will willingly give her my date of birth too?  Not a chance, I hung up on her. 

We have now called the police. 

It may well be a typo on the email, but never was I told that the little bit of information I gave did NOT agree with the loan.  I was only told that if I didn't give the information that I would be held liable for the $400 loan. 

Criminals - It's either a phishing scam, absolute fraud, or a mistake.  At this point, I've ruled out mistake because of the way I was treated on the phone.
