I dropped a couple bills in the box there outside and they never made it to their destination. This is really lousy because now I have late fees to pay because of this post office incompatibility. How often is the box checked and is this done thoroughly because people are counting on their mail getting to its location. I am really upset about this because yous dropped the ball here. I know it’s Christmas but this was a month ago now. So, where did my bills go??? You deserve no star rating I was forced.
