How do I get in touch with the Post Master over this particular post office?

I am having delivery problems. I consistently get other peorple's mail. Yesterday, I did not receive any mail. Today I checked my neighbor's mail box and found my mail in his box. He has moved to Florida for the winter. Had I not checked my mail woul d have been in that box until he returns. My address is 22928 Pilcher Rd.His address is 22926 Pilcher Rd. Please inform my carrier to be more careful and observant when delivering the mail. My neighbor's mail at 22926 is to be forwarded to his address in Naples, Florida..

This did not help me! It just backs up what i said about the problems they have.
