I am receiving e-mails and phone calls from this number from a company called CashUSA who is threatening me that I will be blacklisted and never be able to find a job again, they are calling my employer, and I will be getting legal documents in the mail.  

i just received the same message for my husband. we never took out a loan. i feel the same way.

I received a email saying there was a legal case by cash USA  I called the number on the email (850-810-5542) the person that answered would not tell me thewith company it was

Yep, I have now received 2 emails from this Cash USA, which I have never done any type of business with...  Indicating I borrowed $686.00, the penalty is $8526.35 and attorney & court fees of $1500+.  I know this is not legit... it is in broken english.  I also know that any legal process must involve actual written legal documentation - not an email.  The email IP address appears to be Chicago, IL, but the phone number comes out of Florida.  The name is supposedly Blake Griffin... he says I will get laid off my job (really?) and I will be blacklisted from getting any other jobs.  My SS# will be put on hold?  Which will damage my credit history or credit report and my income paychecks will be put on hold...  Ridiculous!  But what bothers me the most is that they have my social security number!!!  Am going through Protect My ID (Experian) for help- got this through Target due to the recent leak of information!

I received the same e mail for the same amount.  I have never had a payday loan from CASH NET USA, BLAKE GRIFFIN.
This a scam.  I wish they could be found and stop them .
