Hello. If I put a mail in my mailbox that I want to send somewhere else with the address, is the mail person take it?


Hello, I am having major issues with my mail. It doesn't come till after 5PM and I am not getting all of the mail. I keep getting e-mails from people saying they sent me things months ago and I never get them, including credit cards. I don't know if mail is just being misplaced, left at the wrong place or what but I am also getting my neighbors confidential mail with their address on it. It's just been a mess and I am extremely unhappy with this right now. It's frustrating.


Arrived at Westborough PO today one hour before closing. Had 50 envelopes with a few pages in each and needed to have them stamped. Was told I was too late. Apparently this is not a service the PO offers. So the clerk gave me a couple of hundred stamps( in exact amount) and I stamped the envelopes. If a " real " business ran its customer service like that they would be out of business.


Why I did not receive my Package
