They are trying to offer some sort of free service but some how it is a scam.  
They call at least twice a day and will not remove your number because they will hang up before you can ask them to.

I got a call from 613-889-9744 today. I have received other calls from that number in the past, but I don't answer. I thought if I didn't they would get discouraged and stop calling - well that didn't happen!  Today I did answer the phone and a man with a foreign accent was on the other end of the line.  I strongly requested they remove my telephone number from their "call List".  Rather than agreeing to do so, he gave me lip!  I hung up!  

Is there some agency I can contact, or a  number I can call to lodge a complaint?  To me this is a very annoying form of harassment, and an invasion of my privacy.

This number belongs to the company I work for, but we aren't the ones calling out.
Some low lifes are using our number as their caller ID.

There's nothing that Bell can do for us. We had to deactivate this # because of the volume of people calling and asking us to stop calling (which isn't us)

One way that you can help us is that if you received this call, please call your provider and ask if they can trace the last number that called you and where it's coming from, then post it on here and we'll try and do the rest. We aren't receiving these calls so we have no way of tracing.

Called to offer me cocaine. I could hear them snorting in the background and what also sounded like gay sex with minors. If you are gay and enjoy sex with minors, you should answer this caller.

what is this number!
