Hello im trying to get of hold of u guys i need to check on my mail if it send to there ?


Been calling the same phone number, and No one ever picks up the Dang Phone. What type of service is this. You're a Federal Facility!!! Answer the Phones !!!!!!!!!


Pure bullshit cant get ahold of enyonethere no wonder they rate it -1 ⭐️. Amazon says they have my package but when i got there there was nothing. You guys gonna get Karma Bigtime i bet you that.


My mother tried sending a card with a $200.00 money order as a gift for my son's wedding, but it never made its way here in Washington State. According to my mother, she purchased the money order, and filled out the card right there and there at the post office in Tamuning. When she was getting ready to approach the counter, one particular female (local) employee EAGERLY offered to take the card from my mother’s hand, put the stamp on it, and mail it for her. My mother found this person’s action a bit peculiar, but she did not think much of it because she had sent Christmas/birthday cards and money orders to my kids before, even when we were stationed in Europe. She's gone back and filed a complaint about this incident, and that card with money order seem to just disappeared in thin air. Currently, my mom is still waiting for her $200.00 reimbursement...


I tried to call the Post Office in Tamuning to verify some information however, they NEVER ANSWER THEIR PHONE !!!! It's frustrating. Why have a number if you won't answer ?!


staff are not very friendly. they dont even smile. and cant answer my question. this filipino guy with the glasses is very mean. need to fire him
