Our carrier has been delivering mail for other residents to our address when it clearly shows the correct address to sent it to (4-5 times). The street number is the same as mine but street name is different. I've just simply place it out on our box for him to pick up. I'm expecting an important letter that was mailed on 8/19/20 but have yet to receive it. I'm afraid it has been delivered to another address. Some people might not place it out to be picked up and redelivered correctly. I hope it gets delivered soon.


problems with carrier...doesn't deliver packages that will fit in our oversized mailbox and puts neighbors mail in our receptacle. Also we leave gate open when we know oversized packages delivery date ( by tracking them) and she will not leave them.


I recently moved to The Avenue Apartments at 6720 S. Florida Ave. in Lakeland. I am disabled and have to use a walker. My mailbox is quite a distance from my apartment, too far for me to walk, so I purchased an electric scooter. The apartment building exit doors are not automatic, so it is difficult for me to push the door at the same time as trying to fit the scooter through the door. When I reached my mailbox, it was at a height that I could just barely reach it and when I did, I could not see its contents and had to scoot the mail out, most of it falling to the ground. When returning to my building, I could not position the scooter to display the key code and get to the door to open it before time ran out and the door re-locked. After several tries, I had to position the scooter at the door and hobble to the key code reader and get back to the scooter in time to open the door before it locked again. This is a real hazard for me because if I fell I could not get back up by myself. I would need human help. So I was told at the local post office that if my doctor would submit a letter stating the hardship I was under, that my mail could be delivered right to my door beginning the day following receipt of the fax. My doctor did, in fact, fax a letter to this post office on June 17, stating the hardship and requesting the delivery to my door. It is now June 19th and I have not started receiving my mail at my door. I am appealing to the post office to please expedite this request for delivery of my mail to my apartment as quickly as possible.


I have been experiencing packages not being delivered and receiving other peoples mail, which I then have to deliver to the proper address on my street. I recently ordered something that I believe has been delivered to someone else. I am loosing faith in the postal service.
