Well, the poor guy that just called me got an earful.  2nd call from these guys today, 4th this week - they even called on Easter Monday!  Exactly the same thing happening for us as for everyone else.  Indian sounding accent, unrealistic names.  So annoying!  
I wish there was something we could do that would actually have some effect on this type of thing.  The Do Not Call list sure isn't working.

I live in Nepean.They called here Apr.16 @ 12:52PM and hung up when I asked them to put me on their DO-NOT-CALL-LIST.They are VERY RUDE and even though I'm registered on the National DO-NOT-CALL-LIST, I am still getting their calls.

The company name is not important because it is nearly always fake. This time they called themselves "GTA Home Services" AND THEIR REAL CALL-BACK NUMBER IS (905) 214-7405. This number really works, but they usually only answer after the second time you call. The first time they will not answer and the phone will eventually stop ringing.Their call display number is a fake number used to hide their real identity. They are usually always offering "Air Duct Cleaning Services" with a 40%-60% discount because they are "in your area" (that's about $100 cash for a 2,500 sq. ft. home). Their offer is unrealistically low and if you do hire them, they are likely to send technicians to blow air around while scoping out your rooms to see if there is anything worth stealing. A proper cleaning should cost about $250-$300.I have been getting these calls for years, usually more than once a week. I gave up asking them to put me on a do-not-call list because they don't care. Nearly all of the callers have thick South-Asian accents but use very American-sounding names (which they will swear are the names their parents gave them). The call display number is always fake and always changes -- so blocking the number through your phone company will only work as long as they keep using the same fake number on the display.When you ask them for their company name, phone number, address, or web site, all of them will be fake. They usually direct you to a fake web site or another company's web site. They usually use a generic company name or the real name of another company who's never heard of them and does not use telemarketing. In fact, I don't know of any serious air duct cleaning company who does use telemarketing to sell their business.I usually ask for a company address and Google it while I have them on the phone. It only takes a few minutes to realize that the address either doesn't exist or belongs to a subway station, UPS store, etc. Then I ask for a call-back number and call that number while they are on the phone to verify its authenticity. Usually the number is fake, but this time the caller (who first called himself "Mac" and then changed his name to "Naveed") gave me a second number which actually worked (but only after I was asked to call the number a second time) -- which seems very suspicious. Naveed then passed me on to his supervisor who gave me a different company name and when I asked to verify his address, he hung up.I called the call-back number -- (905) 214-7405 -- and spoke to "Andy Marshall" (another South-Asian) who claimed he was a supervisor and promised to put me on their internal do-not-call list. He said that he works out of a house in Mississauga with 25 other people, but the address he gave me was fake (it belongs to a hospital). He also said his manager's -- "Joseph Anderson" -- was "in a meeting" and couldn't be bothered. He said that he knew about the national do-not-call list and didn't care because his company was trying to tell people about their promotion and thus said the do-not-call list did not apply to him. He said that he's been with the company for 2 years, but also said that the company has only been around around since January 2012 (only 3 months).Finally, when you ask them, all of these callers will claim that this is the first time they have ever called you, and then try to explain that there are a lot of other air duct cleaning companies in the area and that you're just mixing them up with one of their competitors -- who evidently also hire South-Asians with American-sounding names, reading from the same script and offering deep discounts on air duct cleaning while feeding with you a lot of fake names, phone numbers and addresses. That is quite a coincidence isn't it?

try removing your number from the calling lists by telling bell and they'll stop callinghttp://support.bell.ca/Home_phone/Phone_line/ ... me_phone_number

Mike. I am legally blind and have never been able to see my call display. I found a program on the internet called Phone tray and it sends my caller display to my computer screen in nice big letters I can see. Of course you can adjust the fonts to any size you like, and you can choose the colours you like too.

Phone Tray is a free download. Although this company does survive on donations but you are not obligated to do so. I have cable connection for my computer, but needed to get an internal modem. (either net card, they are less then 10 bucks to buy, but getting difficult to find now a days in Southern Ontario) When a caller comes in and I don't know who it is, the program has an option to click on, 'online look up'. This program depends on people like me to supply the first time entry to log into their information. I come here to Who calls me to find that info then give the feedback on Phone Tray.

You can click block caller and send to block list. This part is neat. I can type in who the caller is, or what it pertains to. I then can block them. OR I can ZAP the caller. Which means after the first ring they will get a very annoying sound, which will cause them to hang up immediately due to the irritation. OR you can give them the silent treatment too.  There is a recordings too, NO Telemarketers. Or This number is no longer in service. ETC... ETC... ETC. You pick out the message you like. There are many for you to use.

I have been using this program now for about 4 years and I would never be without it. It is a god send for me and I just love it.  I get the last laugh on these these nuisance calls. Oh and the calls are logged in your block list. You never have to deal with them again because they give up on calling you.  It's no fun for them when they don't get to harass someone like you and me. Sure they could end up calling you from another number they have, but you do the search on Phone Tray's look up, or in here on 'Who Calls Me." and then you put them on block.  Phone Tray can be found on Cnet, Tucows, Downloads.com etc.   I hope this helps you all in winning this battle.

Calls and then hangs up repeatedly
