I have a customer that owes me $145 for a spring clean up done on march 13th. This customer recieved a statement ever 15 days once it went past 30. I never heard a word from this customer even after sending a statement that she would be sent to collections. On Monday we were in the area mowing another lawn so we decided to drive by her house. My partner stopped and knocked on her door. He was very polite and simply stated who he was and that he needed payment on some services we provided. She rudely told him to go away and shut the door. On the way down the driveway he made a comment to another contractor working on her heating/air and stated "I hope you get paid for your work." Shortly after i get a phone call from her claiming we had harrased her and that she was going to sue us for "defamation of character." She also told me that it was "illegal to send a thug to her house to demand money". My main question is where does the law stand on this? Is it illegal to knock on someones door and politely ask for your money? Is its "defamation of character" to say that to another contractor? There have been a few conversations with her since then but this post is getting winded. Any help would be greately appreciated.
