Today I got 7 calls and hangups from this number

phone call from this number has a dead line when I answered it, then after a few seconds there was a 'hello',  I didn't engage in conversation.   When I tried to call that number the recording said this number is not in service.  how can that be?

Victor and all his friends continue to call and try to sell me air duct cleaning services.
How do I get them to stop!!!

phone number 416-661-7619 is abusing people , Just call police or your phone company toreport abuse, and they will stop to call you.they are not duct cleaning company.

its an air duct cleaning company
