Postal Locations

I live on a dead end road. And I just saw the mail delivery vehicle drive in the ditch and then across the end of my driveway and proceed to drive across my lawn on the other side . Basically just did a loop. I’m sure it was a substitute driver. Because the usual one pulls up past the driveway then backs up into my driveway to get turned around to get to the mailbox

I put 8 legal sized letters in my mailbox on Friday after the mailman was already gone. I wanted to make sure they were picked up on Saturday the 12th of February. I had them all stamped and had a rubber band around them and when I went to get my mail, there they were, but the rubber band was gone. Now why didn't the mail person take my letters? This is not the first time this has happened. I never have a problem any other day, just on Saturday. Please check into this for me please and find out why this person is not taking my mail.
