cashnet.usa harrassing phone calls to collect fraudelent debt Internet

i have gotten no less than thirty calls from some man with either indian or pakistani accent calling himself DAVID WHITE stating that i owed for a payday loan that i never got. i urge anyone else who has gotten these calls to call them back repietedly as they call you the number they called me from is 831-295-8472 .I figure turn around is fair play. they threaten with jail , court ,and negitive credit reports. as far as i know that is against the fair debt collection act. i have been told nothing can come of this but i have vowed to myself to have as many people i can get to call them as much as they do. i figure if they are dealing with there own harrasing calls it will be harder for them to call people to scam
