TLDR: I received full refund for 2+ hour delay.
Kept my flight rather than cancelling. On the day of I noticed it was delayed. Delay showed over an hour. Called. De-Icing - Big surprise. Delay then showed over two hours. Called Chase. An hour of Chase dealing with WestJet to get some vouchers, which once obtained apparently take 30 minutes to input and refund points. Had it all approved for full refund. I was almost 1.5hr into phone call when I had to board a plane and the call dropped. No call back even though I gave my phone number for call back. After my flight I called again. At this point delay showing 4 hours. Took another hour with Chase but I got a full refund.
