Como faço pra rastrear a minha correspondência?


Sat. 8/5 approx. 11 am. I was in a hurry to mail something to family probate court in Cambridge MA this morning. I didn't have the complete address. I asked the employee if she could help me. She said, "Can't you just Google it?" My phone was in my car, it was pouring rain, and I had an appointment to keep. Needless to say, the post office is closed and I still haven't mailed this important time-sensitive document. I am very busy taking care of my mom who has brain cancer and her husband who has alzheimer's. Thanks for being lazy in North Chelmsford today. Outstanding customer service. I know that if I had gone to another post office, they would have helped me, it would have taken just a few moments, and I wouldn't have to juggle an extra trip today to a 24 hr kiosk in downtown Lowell on top of everything else I have to do. Thanks so much. Sorry I interrupted your conversation with your co-worker.
