Need to verify delivery address of a package I sent this morning from a post office. I wrote correct address on my handwritten label, but I THINK that when the postal worker entered it into the system for me to verify, it was incorrect on the screen. In my haste to leave (I was late for work) and my scatterbrain I didn't catch it. I need to verify what the address is in your system to make sure that the package gets to the correct place, this is a time sensitive package so I want to make sure it goes where it needs to and that the destination address is correct. I cannot verify this information on my receipt or via the tracking number so I need someone to call me. I left a voicemail at the specific post office that I went to for them to verify but have not received a call back. thank you!
