i get a letter in the mail dated 1/21/09 from a past due customer from this past season. says hes not paying because i charged him for a lime application that he did not sign up for nor request or even recieve. so this guy owes for 3 treatments and has been getting monthly past due statements and phone calls with no response, and finally responds now with that! turns out he did return a signed + dated contract to me requesting lime, he did get a lime application and an invoice on 8-22-08, and i even scheduled this with the customer as his family was going on vaca and wanted me to treat while thay were gone. this guy has been a historically slow payer, now is he seriously trying to weasel outa paying?
