This is an Indian company that calls all the time to offer "professional duct cleaning service". When i explained that we are on a National Do not call list. they either hangup or just say their number is (416) 345-6000. The last person that called is "Max" from India and hung up on me. The National Do not call list is no longer a deterrent for these very rude offenders. I wish Bell Canada and the government took these offenders seriously as they often bother us a dinner time.
