I've also had to cancel/refund several flights this year over the phone, and pretty much all of them the agents initiated the refund and I didn't have to do anything.

However, there was one exception where after not getting a refund after a couple of weeks, I ended up submitting the request through the website to get a refund.

You can also check on the refund status through the same link you provided.
