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 !!
