Anyone here experienced WestJet (or other) gift card fraud?

Getting the run-around between Costco, WJ, and my credit card.

WeatJet tells me I'm lying and won't provide me with a transaction history on the GC. Costco is still looking into it. Says I should also go to the RCMP. Credit card insurance won't deal with gift card claims, presumably due to rampant fraud?

Anyway, I purchased a physical GC from Costco in January. Tried to use it in February but when I scratched off the pin and entered the info, it said it had a zero balance.

I've successfully used other WestJet GCs from Costco.

At this point I'm essentially screwed out of $450.

Happy to trade notes with anyone else that may have experienced this.
