[Summit] mail misdelivered

[Elizabeth Grossman]

Hi   I remember seeing on the listserve some postings  not too long ago about misdelivered mail.  Today a neighbor’s children very kindly brought to me about 10 pieces of mail that had been delivered to their house which was  in the 170’s on 8th  street .. we are in the 130’s.    
Do you have any suggestions whom i  should contact to complain about this error? .  (I apologize for asking for info already posted).   Thanks so much. Elizabeth
