Driver calls me on my cell phone saying he is at the building entrance & can't get in. I told him to go to the panel to the right & push 106. He says that he is & of course there is no buzzer going off in my apt, so I tell him I will be right down. I get to the entrance & he is not there. He then calls me again says he is now at my apartment. I am thinking he took the stairs while I took the elevator I go back to my apt, he is not there. So I called him asking where he is, because now I am at my apt & he is not. Turns out he went to the wrong apt building. He went to building 5411 and I am in 5211. Building signs are clearly marked.
