Is there anyway I can find out who and why our mail delivery continues to put others mail in my box? What should I do with it?

I think we need to call one of the t.v stations out maybe that will help get them figured out it's every day

Take to post offfice and ask for postmaster and file a complaint in person. If that has no effect then it time to call Sacramento.

Call the USPS Consumer Affairs office and file a complaint. You should also report it to your local postmaster. If possible, take the misdelivered mail to your designated post office and explain the specific problem. Before you return any misdelivered mail, be sure to scribble through the barcode stamped on both sides of the card or envelope. The automated barcode generated in the sorting process has everything to do with where mail ends up. If you don't scribble out that barcode, there's a good chance you'll just get the same mail again in a day or two.
