I am a clinical nurse coordinator near and visit this p.o. frequently. However every single time Rory assists me, he is very rude, inappropriate, and hostile. I have always tried to be professional with him, but he lacks any professionalism. And I've seen him treat others this way as well. I'm sure you have heard this before. Thank you


3325 Bayshore Blvd, 33629, Mailboxes in Atrium. Packages too big for box are left in open Atrium, not delivered to the door as has been the practice in past. Problem has begun in last week or so. Anybody, service people, or others, have access to atriums as there are several entrances in each of the of the wings. These are USPS, UPS, Primo and this past week a pkg from Canada Post (assume USPS handled it). In the past there have been packages that were not received by addressees -- but were left in Atrium.


I have a different mail carrier every day, they come at different times every day and very often they drive right past my house when my flag is up and I have outgoing mail in the mailbox. I have complained to my local post office and never have received a response. Where is the consistency and the decency to follow-up with a customer or pick-up their mail?


Never answers phone for customers. Phone rings and rings, then goes into a fast busy signal.


That's what is happening to me as well. Did you ever get resolution?

Hi. My name is Bridgit and I am a funeral director in Houston, Texas. (Another hot spot for the virus.) Today I had a loved ones' cremated remains delivered to a family in Tampa, Florida. While understanding the importance of social distancing I find it repulsive to know that the USPS postal delivery resulted in the "package" being left at the door. In my eyes, it's like leaving a BODY on the FRONT PORCH. We pay for a signature for a reason. In which one was not taken.... and the box is CLEARLY marked "CREMATED REMAINS" on the outside. This is an issue that most certainly needs to be addressed and prevented from happening again. You can't just order another father's ashes on Amazon if someone takes the box off of the front steps. They didn't even ring the door bell or knock. I am seriously disgusted by the lack of moral and care that my family had to discover. I truly hope this doesn't happen to anyone else ever again.

At apartment buildings magazines, AARP bulletins, Medicare booklets, etc. etc. are piled for anyone to take on the counter. Even though each one has a printed name and address. I did not get my Medicare Booklet for 2020 or my AARP Bulletin because whoever wants can just walk up and take it. We have private mailboxes but the carriers are to lazy to use them. People sending ads, info booklets, AARP, pay postage to get to a certain mailbox. Mailing lists are purchased to hit certain addresses and people. This I believe is breaking a law of some sort.I pay dues to AARP and pay Medicare. etc. I do not appreciate the carriers dumping it for anyone to take ......poor job poor supervision poor job etiquette.
