This information is WRONG...THUS USELESS. Update the open hours...I should have not been fooled by this useless website


i had a package come to you that you where to deliver to me i did not recieve it,the tracking number is 92612909985309720160339,specific beauty said that it showed that it was delivered,for some reason i have not recieve other mail that has been sent to i havent recieve, i dont know whats happen if some one is messing with my mail but, specific beauty is sending me another package please deliver it to me. RUBY TATUM,22078 ARBOR AVE. 414, HAYWARD CA. 94541, 209-460-1940.


Called for 2 days straight. No answer. Rang many times then it goes to 'busy' signal. I have no way of getting there. I tracked a package and according to their status, it was delivered yesterday to 'person'. It was not. Ordered gift for grandson and did not receive it. UPS, FED EX, or DHL my friends. Do not use USPS. Now I know why they are in dire straits.


Called for one hour and the call went unanswered except for one pick up and hang up as not to deal with the calling. A package was delivered to the "Business Door - Porch" at my business and a staff person was in the office.


I would like to say this is the worst post office ever. They never answer the phone,the customer service is not very friendly at all. They never smile! They look like they are so unhappy to be there.
