In Toronto - also just recieved a call from this # - didn't answer, then looked it up here.  Just informed people I know to beware as well.

These spammers are annoying....  I never know myself being a Costco member

Just got a call didn't answer it.
If this number is no longer in service how is it still being used?  Is there no regulatory body that looks into this?

I got the "Costco" call "because you are a valued customer" ironically, whilst I was at the Costco gas bar. It was identical to a "Telus" call I got which was a phishing call...just like the bank phishing emails. Don't fall for it.

Said "because you are a valued Telus customer, press one to claim your prize"Didn't sound right to me

Just got a missed call from the number too. Called it back and said it was disconnected.
