Upon my first visit to the post office in Central Islip NY, I was called to the counter by someone who was clearly agitated by the name Michele Gordon a supervisor within the Central Islip Post Office. The reason for me being there was to change my address since I had not done so recently although I changed the address on my license here in Suffolk County New York. I was told by the person to which I live with, that she had changed my address, since that did not seem correct I decided to check for myself if my address had been changed, which it wasn't,thus the visit. Michele again clearly agitated upon my arrival, had a brief exchange of "need some help here" with a co- worker at the counter and thus was agitated before I even arrived. She basically refused to do her job concerning imputing a change of address form into the computer with a supplemental for previous addresses, which I felt was needed. Because of a problem of Identity theft and other issues, which I did not feel at the time I needed to discuss, she refused to accept my change of address with the attachment or the form by itself, handed it back to me and walked away. Thus I asked for her name, since obviously there have been other complaints, Sincerely, Patrick A. Miller
