Fedex — Cutting across my yard.

Good afternoon I'm sending a email in Hope that you can stop your drivers from going across my yard. We have sent in a complaint before and someone called saying they could replace the grass etc... that is not necessary. I want your drives to respect my yard and not be lazy and back the dang truck up! I understand they are going to my neighbor house but cutting across the yard is not the way. I use FedEx alot and if it can't be fixed I'll find another way to gave my product sent to my home.
