I understand that having residents in the center of town pick up their mail at the post office is a cost saving measure, but I, for one, leave for work before the post office is open and return to the area well after the post office closes. Typically, my only day off is Sunday, which doesn't help at all as far as picking up my mail. It's frustrating. Oh, and I was charged for my P.O. box because the other renter at my address already has one.

I am very discussed with the postal service we receive on Hopewell Dr Clayton De19938 My neighbors and I always have the wrong mail we are always having to switch with each other so we have the rite mail There has been mailboxes hit by postman’s truck and broke I had certified letter that where never delivered I have watch postman put mail in box and go get it to find certified letter thing saying hevstop and no one home while I was standing rite on my deck he never approached the house to make an attempt And today 07-12-18 I had a package delivered My daughter watched him just throw it over the gate on to the deck luckily didn’t break but enough is enough I would hope that something may done about this but I know several people that have complained and nothing but one mail box fixed I have gone to office in Clayton and complained but it just keeps happening I like to know what it takes Hopefully someone will read this that cares about their job People at office don’t answer phone or return calls So I guess we will see
