I definately agree with comments from shell. This person calls for duct cleaning and very rude. These people should be reported some where and somebody who knows what to do should take action.

Almost 3 times a week for at least 6 months now I receive a call from idealhome cleaning services  from a number (905) 595-8628 and asks me If I want my ducts cleaned.  I reply each time no I don't need your services, I had it done already, thank you.  I been recently asking to be taken off the calling list, and they say no problem but keep calling me, I spoke to a manager and he was so rude to me and insulted me and then hung up.
