United States Postal Service [USPS] review: mail delivery

My name is Mary Gavaghan of 530 Michell Street Ridley Park PA. In 53 years I never had mail problems. I'm very upset and angry. I have not received christmas card from my son, and now 2 Valentine cards, one from my great grandaughter and one from my son. They spend money on these cards ...they are not the dollar store and they are really angry! I called the local Ridley Park Post office [protected]) and tried to tell a "Robert" what my concern was and he was very arrogant with me and told me to get online and complain and hung up abruptly. I feel as though my postal route now handled with 3-4 different people aren't delivering mail correctly. Of course you would think neighbors would bring it to me ...but i can't be upset with them when it is the GOVERMENT workers that aren't doing there job. Please get your postal workers together and get tis problem fixed.
