I got a call this evening and could not understand what he was saying (heavy Indian accent) other than duct cleaning and he knows my name. I do recall getting duct cleaning in my old house and he did mention my old address. I pretended I have to ask my husband and got their number of 647-921-7623. Haven't tried it yet but I'll use Google talk to call them.
I also received a call from this number at around 5:40 PM.
I let it go to voice mail.
They did not leave a message.
Clearly just another time-wasting solicitation call.
