Never received my package and showed it was in the lock box . But there was no key for me to open the lock box.Must have put the key in the wrong apartment box or never delivered it to the lock box and now I have to try to get my money back .

Joann is a very respectful, kind, professional, competent postal clerk at the Middle Island Post Office. I finally had a chance to give her a review; she has been there many years. She is a definite asset to the postal service. She always has a smile and always polite.
