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

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

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.

Called it back, it's Westjet telling you to call 888-westjet.

This # is WestJet, which they are calling back. Had phoned them ref a reservation, they were busy, so they eventually called back

Westjet....this is their number when they "call back" from Westjet auto message centre.

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