Postal Locations

To whom it may concern, I have been going to this post office for over 15 years. My mother went in on the 12th and was treated very poorly by the clerk who was middle age African American woman. The clerk was very rude and unprofessional, she had my mother upset because of the way she was treating her, that my mother didn't put a return address on the birthday card she sent me. I have tried calling the location multiple times and no one has answered not even a voice mail to leave a message. This is not the fist time this clerk has harnessed her. My mother said every time she visits this post office the clerk is always in a bad mood, hateful, extremely lazy, and not helpful at all! I would like to see my clerk smiling and happy to be there! At this time it is lackin terribly! I woul like to be contacted so I can have some questions answered.
