Payday loan Netcash

Called me and said they had a faxed complaint against me. They said I had a Payday.loan 2014 Netcash . Told them I never took out a Payday loan in 2014 . They.said they were going to serve me at my house or business. I ask them their address so I could serve them with papers. They said they don't give them out. Called Netcash and they said they don't deal with In house solutions. It's a Scam.
