Signal Mountain resident Ann Ploetz said that since last December, her household mail has been arriving later than usual. And sometimes, including a few days last week, she doesn't get mail at all.

"I've been in the post office, and I've heard people complaining and complaining," Ploetz said, adding that community Facebook pages for Signal Mountain residents are filled with comments from neighbors with similar issues." Things have been really bad for about eight months now."

Hixson residents have also gone to social media with delivery complaints, mostly related to packages that never arrive or arrive days after they are "delivered" when tracked online.
