The Harrington post office losing my mail. Been going on for a year .Al the time. Does any one know why or having the same problem ? I have never nothing like it.


Can anybody help me, possibly tell me How much the stamps are at the post office anyone know for sure? I have to find out asap trying to get some this morning so I can send a letter off today when mail runs..


I went to the Harrington post office today. The gentleman that waited on me was so kind and nice and had a smile on his face it made my bad day so much better. People can be so nasty this time of the year and with all else going on he made my frown turn upside down. Thank you


This is the THIRD time the lady “forgot” to put the key in our mailbox for a package!!!!! She’s on her phone the entire time putting mail in boxes, cussing and yelling the entire time!! EVERY SINGLE DAY!!!!!! If it were something medical like meds or supplies I needed today, I’d be screwed!! This HAS TO STOP!!!!! It’s ridiculous! I understand 1 time but 3?!?!? She needs a job in telemarketing being on the phone driving the entire time!! Just drove in the rain to find this out and now they have to figure out where my package is!!!!
