We are a rental fence company. We do a lot of our business through email. About a year ago we got a job for rental fence from a lady named Julie VonKohn with the signature on every email saying Julie VonKohn Executive Assistant Machine Guns Vegas. We named the Job Machine Guns Vegas. The place they had us put the fence up was leased house. They sent an email telling us they wanted to cancel the fence because they where terminating their lease with with the owner. Since then they haven't paid. We liened the property. They have called and said that we are using the wrong name on the lien. It is suppose to be XBoat Ride LLC. This is the first I have heard this name. He said that Machine Guns wont stand up in court.? Not sure what I should do. The lien is on the property and the company name is Machine Guns.
