Received a voicemail on my cell stating that I had recently applied for a payday loan, and was pre-approved for $1,500. They then proceeded to tell me that I can apply at mypayusa.com with a pre-approval code for up to 24 hours.

Obviously, the above is not true.  It's just another one of those robocalls.  I blocked both this number, and the one as indicated on their website:  1-855-531-8909.
