Who called from 9257752256

Kept getting repeated calls demanding money as well as personal info to be transmitted via fax I.e. Drivers license and address

I recieved numerous calls from this same number wanting the same info sent to them, they also wanted it sent to two different fax numbers and said that it had to be noterized.  They are saying I owe 1245.75 for a payday loan I supposedly took out in Oct 2009.  I haven't taken out any loan at all and when they call the have said it is from three different loan companies three different times they called.
