A lot of my mail is been last I been paid late fees on my credit cards because my mail is getting last this mail person is sacks please do some thing


I live less than a mile from this office, so it's my office of choice. I occasionally sell online, so I post packages. I also have overseas friends I send letters and the occasional package to. The people in the SJC PO have been unfailingly pleasant and helpful even when I have made a mistake or don't have a clue what I ought to be doing. German addresses can be tough! Any customer service job is tough. The DMV and Post Office get a particularly hard rap. Maybe I'm just lucky, but I've always gotten good service from both. Maybe because I start off being nice to them. The honey and vinegar thing, right?


The horrible postal service is beyond horrid!!! I have made several efforts over the last 2 years calling phone numbers posted....not once has any one answered!!! I've tried both numbers... how incompetent can any be to this level...obnoxious!


I ordered 1st class postage stamps on 10/21/19 Check #6793 for $11.00. My check cleared, but I didn't receive the stamps. I've contacted every P.O. close to SJC w/no results/response. I sent my check & order in a P.O. envelope! Please send stamps. I'm unable to drive, thus the email. I'd really appreciate your attention to this. Thank you. N.S.


It's 530 Monday September 9th I have not received my mail yet


Hi There! How much for PO Box rental (yearly or 6 mo.s please) Thank you :) Holly


SJC post office facility is the MOST incompetent, UNprofessional address of ALL addresses!! REPEATEDLY, I have encuntered incompetent, UNresponsive employees at this unit!! Tpday, 2/5/18 is status quo for this installation!! My first call (949) was eventually disconnected due to no answer by this number. I called the ;800 # with recording there would be 1 hr+ wait! Nearly that time frame, I am STILL on hold with music I'd rather NOT hear!! NO answer! MY tracking number indicates deliver was to have been 2/1/18. Today's date is 2/6/18 and I have NO DELIVERY! There is a reason why your company is a loser - failing with fall off charts , & NO prediction for survival!! S. Larsen - SJC !!
