First time someone called and was laughing in backround, like a crank call, i said hello, no response. Immediately called back asking If I had "muffin pans", I asked "who are you trying to reach?", they had no response, then again asked if I had "muffin pans" once again " who are you trying to get ahold of?" Thinking maybe a wrong #. Then they abruptly hung up. Obviously with no answer for who they were calling or who were they trying to get ahold of, immediately qualified this as a crank call, to harass.
