Who called from 7789459898

The same "As a Costco member you have won a prize, press 1 to continue" that others have been getting on other 778 numbers. Hung up without pressing 1...

Same here. I did press 1, then it was music for waiting someone...then I hung off.

Also called back and recording says number not in service.

Just got a call from this number. They said "Hello. Because you are a valued Costco customer, you have won a prize. Press 1 to collect your prize." It is the same voice that says I am a valued Telus customer, but from a different number. I am neither of those things.

Also tried a callback, but the number doesn't exist.

also just got a called from em. did not pick up
