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

unknown number calling

Been getting this number pestering my line and leaving an access of 3 messages per day for the last month. Called back it was Westjet told them to take my number off the automated call list computer, told me they would take care of it and so far nothing happened, it is even calling around 9:30 pm I have to shut my phone off now. Really annoying it is driving me crazy.

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

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.

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