The service is awful. They lie about leaving packages in your box and dont even leave a slip to pick up at the post office..just throw everyone's mail together..and dont bother to call the local post office in Trinity because you are never going to get anyone!


I don't know what changes have taken place but they definitely need a new Postmaster. Horrible service! Half the time we don't get our packages, they say it's been delivered but it hasn't. The phone number is always busy, you can't get through to anyone to get assistance. Very frustrating..


Sorry, sorry service packages are EVER delivered, a notice left in box, but not always. Have been to post office several times picking up holiday deliveries, YET, saw on retailer website that 2 packages were returned because “no authorized recipient available”. HOGWASH. Not just me, whole neighborhood treated similarly.


Never get my orders because of address at home. They need to find me at my house address which just happens to be my address for 911 which is the emergency address.


I’m not receiving mail or having mail picked up at 3969 Fm 356 Trinity Tx 75862 ... I would like someone to explain why !


Horrible customer service package was said one delivery date but didn't come. I called and was told I could come in and pick it up and once I walked in i was told I couldn't pick it up. I'm using ups or FedEx from now on!!!


when the person sends out our mail they give it to the nabores and they have to always come and give it to us those mails are vary important and we dont wait our mail being sent to someone else we live in 9001 san joaquin trial texas fort worth 76118. can u please start sending them to my house because these envolpes are vary important and they always have to come and give it to us if they have to do that then whats the point of the post office in the first place.


A package of meds. was delivered to Trinity, Tx. it is in the post office. I can not get ahold of them. They have a change of address but it was out for delivery Fri. but not delivered. The proper address is on their change of address.. 22145 Old Nacogdoches Rd. New Braunfels Tx, 78132.. I need these meds.
