A Man Tried to Come Into My Apartment

At 1:07pm today, the maintenance man who works at my apartment complex used his key to enter my apartment without knocking and without my permission.  I did not place any orders with the management office for repairs or work of any kind.  There was no notice to residents of work needing to be done in this entrance.  When I asked him what was he doing here, he claimed that he had the wrong apartment.  I called the management office downstairs to report it and I tried to report it to the local police but the officer was asking me for my name and birth date which I did not feel comfortable to give him and he had an attitude with me in his tone of voice pointing his finger in my face.
