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
