After pick up the phone no talks, When I called back says mesage box is full Really botheration

They keep calling me. I say "Hello", they say nothing. they annoy me.

I am also on the DNC list, but every time I try to get some info to get them stopped, they hang up.

This time, I played along.  The automated message said they were from "Credit Card Services".  When I spoke to a representative, he asked if I wanted to lower my credit card rate.  I told him I did.  He asked if I had over $4000 in credit card debt, I told him I did. (even though I have no credit card debt.)  I was trying to get to the point where he would ask me personal information so I could question him back.  

But then the curious question happened:  "Are you over 70 years old?"
I replied no, thinking a credit card company would be interested in younger people.  With that, he hung up.  

It concerns me that they are targeting older people exclusively.  My grandparents would probably fall for this-

The call came in - Caller ID had the number and "Ontario".  I listened to the auto message and then pressed 4 to get the live operator.  Got a guy.  He started into his routing when i interupted and asked where they got my nimber.  He replayed that they do not have a list.  I started to then say take the number off the list - "What part of 'We do not have a list' do you not understand?" and then "If you don't want our calls then unplug the phone and shove it up your a**".

I don't answer calls from numbers I don't know, I am also on the "Do Not Call' list.

Have received numerous calls from this number.  Last week my wife told themto stop calling us as we were not interested.  We then received two phonecalls at 4:20 and 4:20 a.m. on Saturday, March 21st with them replaying mywife telling them not to call us.  This number needs to be investigated andshut down by the Canadian Government.
