CashnetUSA Claiming I owe money on a loan I never applied for!!! Internet, Arizona

I had previously taken out a loan with CashnetUSA over two years ago and had payed them off back in the summer of 08.  Now I receive a phone call from my mother stating she had a lawyer on the phone stating they were going to issue a warrant for my arrest for check fraud.  Needless to say I was in total shock I had payed them off and have not taken out a loan since. First why did they call my mother who is in another state and how did they get her number and why was I not called.  Second of all I know this is a scam due to I had issues with other companies calling my place of business and my cell phone over a year ago claiming I owed them money as well.  Now I am noticing there are other individuals who are experiencing the same thing.  Whatever you do do not take out a loan with this company they are a scam and will try to scare you into paying them money you do not owe them.  Do your research and don't take their word for it!!!!!!
