ME TO This is very disturbing What can we do to stop these type of calls
I also get calls every day from different cities in the United States

I had left a message for them to call me

Nothing has changed, Westjet auto dialer is  calling on weekends 10:30 pm and some week days. Thing is I never called this company or ever had anything to do with it, and their auto-dialer is still calling me. This is been going on two years now! The recorded message says, "This is the call back that was requested from West jet"...........I press 7 to cancel the call back (from auto dialer voice options menu- the auto dialer voice says "your callback has be canceled." The auto dialer calls back again come Saturday and Sunday and even during the week when I am at work. I am with Bell Canada and they cannot do anything. There should be a law to fine Westjet- really wish someone could help me.

This is true - It's a call back number from WestJet.

Confirmed, I called West Jet and instead of holding on the line for "the next available operator" I chose to have them call me back.  They gave an estimate of three to five minutes wait time and sure enough, a few minutes later their call back showed up as (403) 444-2113.  At first it sounded like an auto dialer sales call; there was that same dead air while it registered on their system that someone picked up. Next there was a recording to press 1 when the person who asked for the call back was on the line.  Pretty smart actually, as it eliminated the inevitable "it's for you" shout out.

if you've given them card info, too late, you've been conned - get on to your card company at once & see if they can block the payment to stop these fraudsters stealing your money; recommend you take PC to reputable local firm to see what malware they've stuck on it, or they'll keep returning for more (you'll need a replacement credit card); if credit company can't help, contact trading standards or CAB, who have experience of these matters, but I think distance selling regs come into it, but don't quote me; consider reporting to Action Fraud (Google their website) to try to get this number shut down before someone else falls into trap.

unknown number calling

It's Westjet.  They're calling you back if you called there and recorded a message for them to call you.
