All of the the post offices in Charlotte have very nice people working for them, but they must be the most over worked people in the world, as you can not reach any of them to ask a question. They are so far behind in in technology its ridiculous. I have a question concerning my mail and not one office will answer the phone. They are holding my mail and I do not know where to go to pick it up. a email system would let me ask them where my mail is. Ridiculous
