Hey the mail person left the mailboxes open and unlocked. Everyone's mail and packages were just open and exposed for the houseless and others to rummage throu or take. Please can you let our delivery driver that does 2155 N.Wahanna know that he left the box wide open and ajar for anyone to get into our mail. It looked like perhaps he/she left and a hurry or had an emergency, to just leave it wide open like that. After figuring it out, with the hinges, I was able to get the box closed. Now is it secure, idk. I tried to call and no one answered the main number line and I don't have time rn to sit on hold calling the 800 number...I'm posting to let you-all know on this date, our box was left wide open. This is a multiple tenant box..

I am sorry to say a package from Amazon for me was left in the package box unlocked. I just by chance opened the box key still in the lock and found my package. It was to be and said to be delivered on 4-8-22.

I've had issue with the Seaside Post Office not delivering my Wish packages but posting that they had been delivered (so I couldn't get a refund). I thought it was just poor service on the Post Office's behalf but turns out it a bigger issue than just Seaside. Now I receive my mail in Cannon Beach and constantly my mail is being returned to the sender and or just never received. In Cannon Beach there is no mail delivered to our homes so everyone must have a P.O. Box in order to receive mail but if the sender of a package or letter labels your mail with your house address along with your box number the Post Office will return the item to sender. Mail can only have a P.O. Box number on it. However, so many companies require a house address and will not mail to just a P.O. Box. So, this rule doesn't allow people the same service as a post office with home delivery and limits our choices of places to receive mail through. Pour service would be the issue if it was only happening in one business but what is the issue when it's more than one business? How does one go about ironing out some of these wrinkles, so to say?

My best friend from Scotland sent me a package, but I haven't received it, even though it's telling her it was delivered to me on the 17th. I have been home every day for the last week and a half, & no package has come. I just tried calling them to see if they can re-deliver my package, but nobody answered the phone.

They are very helpful. Thank you Parker for your patience and for helping me send my packages the fastest and most cost effective way. It would be great to have more windows open especially when your alone and the lines are long. But you apologies and do the best that you can.📦✉📫🌎
