Who called from 9014664777

Calling about a loan that I've done which I haven't I gotta pay $300 or I will be paying fees I it will be $2000.00

Phone calls mean NOTHING -  not an official method of notification.

Most likely a payday loan scam.  See:  http://mrnumber.com/1-901-466-4777
Ignore and block the calls.  If you calll that number you get this strange wierd hold music.  The same hold music I've heard on off-shore Caribbean-based  debt scam groups.  As I say, ignore and block and DO NOT return the calls.
