just had this number pop up never answered

They call me twice. Did not leave me a message when they hung up.

It must be profitable for thes scammers otherwise it would self correct.

Same...Received call but no one speak from other side. Ignore them

Pre recorded message to do a survey for a free cruise..called me on my telus line

If your cell phone has a block list, and i'm sure most do, you can just add it to that list so they won't cb. Knowing telemarketers though, they'll just keep trying with different #'s.
