PSA "Loyalty" Scam

Yesterday I received a call from Alberta 403-915-2871 claiming to be from "Telus Promotions" and telling me that because I am such a loyal customer that Telus has decided (magnanimously) to reduce my mobility bill by 30% and to use my rewards to gift me with my choice of an iPad or a Samsung smartwatch. This amazing gift will be sent to me, at no charge! Sneaky scammers - asked me to confirm my postal code, which gives them my street address, and then to confirm the house number. This is how they get your address while you think they had it all along. They also asked for my Telus PIN and email. When he transferred me to a "supervisor" the connection was extremely bad (bad internet in India?) so he called me back, this time from Ontario using 365-226-6304. This person repeated the same stuff and confirmed the same information. Today I got yet another call, this time from British Columbia (778-557-2619). I told him flat out that I know it's a scam and to drop it. We'll see if the persistent creep calls back again, and from where. When something seems to good to be true, it usually is. 

I have changed my password and PIN (using random generators), activated 2FA on my Telus accounts, and contacted Telus directly.
