I had a lawn cutter service that provided services summer of 2013 without sending me bills. At the beginning of the summer of 2014 I told him if I didn't get bills I would not be able to use him in the future. Which is exactly what happened. Today (2/4/2020) I've received a bill for $898 for 2013 and $1,100 for 2014. Do I have to pay the bill. I think it's outrageous that after all these years he expects me to pay these bills.
