Don't waste your time tryng to get any type of response from this location. It's absolutely the worst! I am a Government Federal emploee that works for TACOM (Army) and they treat me like dirt! All I wanted to do is have my held mail delivered 7 days earilier. I was on assignment at Fort Sill, Oklahima, helping to keep our nation safe. My assignment schedule had been shotened while I was gone. So I called this location to have my mail delivery restarted. After calling 6 seperate times, and after the phone rang approximately 9 times each time I called, I was disconnected? Then I phoned 3 more times from another phone, same results. One time I was connected to a recording that stated I could leave a message, but I couldn't because the message receiver was full and then I was disconnected. I did connect with an operator 1 time. She put me on hold for a half hour to get the manager. Once someone got back to me after a half hour wait we were disconnected?!?! Of course they didn't call me back. I then called them back, repeatedly, and no one would answer the phone? Whomever is the manager or manges this location should be fired! The only way to get service here is to go physically to this location. Good luck!!! If we army folks did our job like they do at this location our national security would be in jeapardy. This is not a joke.


I sold my house put a hold on the mail. My batch of mail had the hold card in it with the new owners mail. I took it back to Warrem Mound Post Office, they had us fill out a mail forward. 3 weeks later I get email that my hold mail is being sent to my sold address. I rush up to Mound Post Office. the Clerk LORI, heard my concern, took my Drivers license, told us to wait for her at the end of registers, reappears ringing up other customers. never came to tell us what was up with our mail. I hollers, what's going on and where is my ID. She pointed to a uninvolved clerk and said she will help us. A different clerk handed her my ID. SO LORI passed my ID around DID NOT follow thru with her services nor informed me of her abandonment of her helping me. TOssed my ID around, never checked on my mail, and LORI pushed off her work onto an employee who was Actually doing some work. RIDICULOUS, Idiots like this are who these idiots HIRE.


Why can't postal employees do their job? I just spent 30 minutes trying to get a certified letter redelivered. I couldn't do it on the website because the handwriting on the form is so sloppy I can't read it. So I tried calling the 188-275-877 number. No real person there either keeps asking for more information. I tried to call the Warren post office and at 4:20 all I get is a voicemail that no one is available. So frustrating. I'm held to high standards at my job and these government workers are suppose to work for us. That's a big joke the have to work first. I can't tell you how many times I've received mail for someone a few streets over. Makes me wonder if I'm getting all my mail.


I just had the same thing happen to me, & had to go there twice to take to Amy. I told her about there Phones & losing my tracked package. It rang 10 times then went to busy. Sad no pride .

Just called , same story, mail box full ...It never changes !!!!!


Mail boxes are full and must call back later or the Warren, MI post office does not answer their phones. Transfer to operator results in call being terminated by the automated system. Very frustrating!!!!


This Post Office never answers its customer phone line; an automated-machine says gives the address listed on this website, notes that a an "agent" will take one's call soon, and then immediately transfers the to a supposed operator, after which one's call rings several times before it's hung-up on by the automated-system--- regardless of the citizen's concern and/or complaint. Just yesterday (on 7-30-15), an employee of the Warren Post Office says that their number changed a few months ago, although no one (not even an automated-system) answers that supposedly updated number; however, both this website and the United States Postal Service Consumer Affairs Office confirmed this number, which I acquired 2 years ago, as being correct. My specific complaints are that I have received other individuals mail (of which carriers refuse to return, the Warren Post office will not answer a phone call to deal with the issue of misaddressed personal mail or any other mailing issue, and just this past Monday, 7-27-15, I along with every other tenant in this apartment complex, received a letter from the US Postal Service (USPS), that as of tomorrow, Saturday, 8-01-15, a switch will be effectively made for mail delivery to go to an outdoor, Cluster Box Unit (CBU), which is a difficult task for an individual with a limited mobility disability issue, such as myself, and likely for seniors, of which i am not, to daily retrieve mail at the designated sites outlined in the letter from the USPS. i imagine that such a task will be even more difficult (and possibly harmful) in the approaching frigid, wintery climate (simply to obtain one's mail). The switch may prove to be more cost-effective and somewhat more accurate for the USPS and the already infamous Warren Post Office, but it will be a great disservice and daily inconvenience for many tenants, such as myself. Both the Warren (Michigan) Post Office and the USPS ought to be ashamed of themselves. Human needs are more important than expending less money and increasing ease for public service and/or corporate America! ~a disgusted citizen
