What about sicking the lawyers on them?

Ever considered a class action lawsuit?  Lawyers will generally work on a contingency basis, i.e. no fees unless you win or get a settlement.

Probably worth a call...

They just called me.  They are Teleperformance Canada when I called them back.  At least I could find out who called.  They offered to remove my name from their calling list...

same here.  I asked them a number of months ago to remove my name from their call list but to no avail.

Hi, I´m from Argentina and now this phone mafia are here too. What are this? the tpgroupinc.com web page doesn´t exist. Their street adresses are in the best cases small apartments. Who knows who this people are?

They called me and saved me over $100 on my cell phone bill.  They are a worldwide telecommunication company that does special campaigns for a lot of large organizations.  All companies are going this route because its alot cheaper than getting in house to do it.  Even our own government has done it with drivetest.  That's why most of you ignorant people that post these comments don't have a clue about what you are talking about.  Don't bi*** and say "why is my bill so high" and "why does rogers never offer me any deals"  Because when deals are trying to be offered, most of you are too dumb and ignorant to listen to what the telemarketer/salesperson have to say before making your decision on whether you want a product or service.  So all of you that complain of high bills and lack of savings, deal with it because all companies are doing it this way!!!!

I also received the call and hang up numerous times from this number before blocking them. Then someone phoned from teleperformance claiming to be acting on behalf of Rogers. After the calling and hanging up I told them I didn't want to talk to them.
