For almost ten years our Callahan Mail Carrier for Sauls Road has delivered our mail perfectly and when there are some packages or large envelopes was kind enough to drive up our driveway. All that stopped in 2020. For some reason we receive the orange slips that say: First Attempt. Not true, drive down our driveway and deliver the small packages. Week after week this happens. Unacceptable. When I place a call I am told the Carrier could not enter the property. False. The Carrier drives by after leaving a notice in our mailbox. Then the Rep from the Post Office tells me that she will ensure that the carrier delivers our package the next day. Guess what, never happened. This needs to be corrected now as we hear that we are not the only Callahan residents not receiving their packages. The carrier needs to do their job or find a new job. It is their duty to deliver our mail which includes packages.


I dont what has been up with the mail man but he has been dropping on our mail later and later everyday. I live off of Marlee rd callahan fl.
