I got a call from them too. It's GDA Home Services for air duct cleaning. I have asked them to stop calling me numerous times and they won't honour my request!

Had similar call today 2:20 (Eastern Daylight Time)PM. agent says they have 50%off cleaning price , asks how big is my house? I reply 5 thousand square feet. He comments that it is a big house. He asks how many bedrooms it has. I reply two. , but it has multiple levels. He asks how many furnaces it has? ,I reply "you mean energy conversion devices", he laughs, but confirms yes, how many? I reply Two, Now here is the kicker, I tell him I have hot water heating (Its the most efficient, but no Ducts), so the Ducks are out back and they just got rained on today,so they are nice and clean. He finally clues in, and then politely says good bye.

This number keeps calling my house daily, no one talks and when I call it back says the number is not in service, how are they calling then.  Its driving me nuts.

According to information I found on another website,

"Phone number: (905) 267-1263 is located in Cooksville, Ontario.  Its exchange 267 is managed by CALL-NET COMMUNICATIONS.  The number is currently on switch number COOKON73713 (switch is a technical specification for phone hobbyists)."

CALL-NET was bought out by Rogers, so it seems that whoever is using this number is one of their customers.

Well got another call again today after he called me yesterday also.  Got a bit more info off of his this time.  He said his name was IRFAN  ???  and the company that would actually do the work is called FRESH AIR DUCT CLEANERS based in Toronto.  I asked him if he knew we are on do not call list, he said he would have to check.  I said well let me help you.  You keep calling everyday now and twice you have apologized for calling saying you realized I was on the list.  This being because I actually agreed to your service.  I told him I was recording the conversation, which I was.  I then report to the DNC complaint site which is what you should do as every complaint will be used against them.  There is a current investigation ongoing as I talked to both DNC and CRTC today about it.  They will not discuss any info but they say they need the complaints filed.  The guy at CRTS even said he gets the calls himself and most of his day now at work is spent talking to people about this problem, so they might actually be working on it, HOPEFULLY.  The idiot on the phone when I said I was recording it said he was sorry and would not call any more.  I laughed and said yeah, I guess we'll see tomorrow when you call again eh !!!!!!

These SOBs have been calling me incessantly for months.  I can't get it to stop.  I even had them to come to my house so that I could tell them to f-off in person.  I called the police and the 'Do Not Call' people on these guys but neither of them would take any action..  There seems to be no recourse.
