I am sick of these guys calling me!! They call almost everyday and are even calling me at 9:30 at night. This is the second time someone has actually started talking without hanging up. He went on telling me that he wanted to get duct cleaning done in my home. Our house is brand new and wouldn't need that service. I told him to stop calling me and i wanted my number taken off of their calling list. He said i'll call you tomorrow and started laughing. I just hung up.

These morons call me everyday, and everyday I say" eat s**t!".  Finally, they called and I had enough.  I said " Sure, I'll book an appt, does that mean then you will stop calling me?"  The indian guy says" Oh yes sir, absolutely!'I say" How will you do this if it's a computer automated calling machine?"  He says " All I have to do is click option D and that will stop calling you"Can you believe this sh--?  Everyday they call, and everyday I say "no and stop calling me!"  They didn't stop calling until i booked an appt and when they came to my door in their heap of sh-- truck i told them to F--- off and stop bothering me.    Crooked little as$holes leave me alone now.

Got a call from this number Dec 18 2010 at 1pm. Did not pick up. Let it go to the answering machine. Caller did not leave a message.

You can block that number from your phone like this *60#(416) 222-2333#

someone called from this # today stating they were calling from Bell Canada, Then asked if I had my home phone service through Bell. I asked why he was asking that if he was calling from Bell and he hung up!
