Bad, bad service, the mail people you guys having deliver mail in our area around 37th ave Malapai have and are terrible. Around 2 nights ago there were two of your mailmen parked in front of our driveway way talking very loudly around 8pm and hadn’t even put our mail in the mailbox until we came outside, then they left , left the mail but didn’t close the mailbox .They don’t close the mailbox door/lid a lot of the time or check to even see if it is closed, they don’t even take or stop sometimes to take outgoing mail. When they do stop the don’t even take all the outgoing mail. This is getting really ridiculous, your guys service is terrible, very , very terrible, they are not delivering all of our mail, we are missing a lot of statements , it is just really bad service.The postal service supervisors need to look into this and get this resolved quickly! Been in this area for 12 years and this is really bad service!! This has been going on since our regular route carrier has retired. DB was an excellent mailman!


Today is March 25th my daughter turned 6 years old March 3rd due to covid and other circumstances in life my six-year-old has not been having the greatest of times a different experience with kindergarten for sure this year even been having some behavioral issues due to no visitation restrictions she currently is very happy and full of joy although she is missing her father who is currently in a prison I received a pink slip in my mailbox a while back but I don't have a vehicle and was quarantined temporarily and unable to pick up my package as I was waiting to be cleared today after picking my daughter up from school walking back through our apartment complex we happened to see two wonderful ladies in the mail room they advised me on how I could reschedule delivery and also would also be able to go into the local post office however is mail ladies brought me to tears as they ended up going to the post office which is not very far and came and dropped the package off at my door these wonderful ladies have no idea how very thankful I am they hold up very special important part in her contact with her father currently for means of communication which is so important one and three children have a incarcerated parent I appreciate them going above and beyond as the package that I was expecting was her birthday present God bless them.


Hello I need to know how the holdail works? I will be out of town for Ave couple weeks but only me. Can I. Put a hold on. Only my mail. And nobody elses at my adress so. They can keep getting thierail but only time I want to be held please if I get back in town sooner I will come pick it up. Tthank u.


Bad customer service, Bad attitudes and bad service. They are refusing to deliver to people apartments during this crisis and taking it back to the post office where everyone has to pick them up. The manager there is RUDE to everyone.


Very poor customer service. Continuous problems with our local carriers not picking up outgoing mail, calls to this office are rarely answered and when they are, most of the time the agent is not responsive to the problem. Very poorly trained staff at all levels.
