I have been receiving mail at 13 Everett Ave. Knollwood, Claymont, DE for over 30 years. These past few days the mailperson is leaving my mail on the step in the rain. I have a mail slot in my door, I don't know why they are not using it. 792-0195


I didn't get the package that states delivery 6/21/20 left at front door. I waited all day. It wasn't sent to this address. I have gotten mail in my mailbox ripped open and written on it stating it was delivered to the wrong address & opened by mistake. My address is 2604 I think mail goes to 2406. Where is my package? $200.00 clothes from Lands end? Dorothy Jones (302)2563436
