Claim to be westjet, get your free holiday or 70% travel. If you get them on the phone, they will ask you "are you over 27 years old?" Never answer "yes" or "no", it’s a scam to record your voice and try to authorize charges to random accounts. They have your phone number listed and your voice recorded. Unfortunately we can’t stop them as the numbers are always spoofed. If you try to call back it’s either someone else’ number or the number doesn’t exist.
