Three days during the last month I have received no mail delivery at all on a regular delivery day. Today I stepped out my back door for the first time in several days because it has been so cold, to put out my garbage. There strewn on my back steps was a large pile of mail for a neighbor two doors away. I have complained about the days without service and no one ever gets back to me. I cannot get through by phone. the line is always better. Surely you can do better than this!!!


We gave you a mail hold for 7837 Aberdeen Road, Bethesda 20814. Our neighbor says the mail is being delivered and left in front of door. You were instructed to hold it until October 30...please correct, and let me know. Irene Mendelson
