Our landscaper suddenly sent us 3 invoices for work he has done almost 4 years ago. The invoices are dated for January 2020. We don't remember if we paid or not. We have no debt and pay all bills immediately upon receipt. We also pay him automatically monthly. He is billing us for random things and extras work that we did have done. He has handled our yard for 9 years and this has never happened. My husband would have paid by credit card for the extra work but he likes to change credit cards because he collects points for travel, so to hunt down which one he was using back then would be very difficult. We want to be fair but even health care has laws in place to protect consumers from late billing. This just seems out of place. Please help... You thoughts?
