Taylor Post Office review: Delivery of mail

I put some mail in my personal mail box on Tuesday, March 15 to be delivered in the area, cards. None of them have been received as of Saturday, March 18. On Wednesday, March 15, I took 10 cards to the post office mail box and mailed them at 930am, not have been received, as of Saturday, all local.
We keep getting other peoples mail in our mail that is not even close to our address and have to put it back in the box or delivery it. I am very upset with the delivery of Taylor, s mail. It just keeps getting worst. Why?
