How should i have dealt with this?

jeeze, i would have been crazy confused if i was woken up by my buzzer i would have probably done the same thing. how could you have known that the guy was going to talk to your neighbor though? you had no idea. i think you handled it fine. i probably would have done the same thing, and been thinking "what the **** is going on" the whole time. you were sleeping! and this woke you up with that damn buzzer! this just seems like a whole "what the ****" situation that you shouldnt have to be involved in. keep your head up! and dont worry about it, come and go.
