no answer when i answered as well, but i have recived a call from this number before and belive it was for air duct cleaning service that deffiently sounded like a scam because they would not take no as an answer

Same thing, picked up the call and no answer.

They hang up when I answer. Carpe Diem.

Have received multiple calls from this number. The last call I hung up without saying anything. They called back immediately and were abusive and aggressive.

Very rude person.  Keeps calling back even though we told him he has the wrong number.  I finally had to add a caller id block in this number.   Also uses the phone number (416) 628-7192 and even tried calling with caller id blocking enabled.
