Reward Card - "Activated" but haven't received it

Hi all,

My partner and I moved in June and set up with Frontier's 500 for $29.99 deal + $100 visa gift card.

On 9/9, we received a confirmation email saying we successfully claimed a $100 visa reward, and that a card should arrive in 3-4 weeks. Today I found the reward center link on another post and plugged in its claim number - it shows card received 9/9 and activated 9/15. We haven't received anything since the congratulatory email last month. Did someone possibly steal it in the mail, or am I jumping to conclusions / misinterpreting?

I've seen a lot of reddit posts about how difficult it's been to actually receive and redeem the visa reward. Sorry to add to the pile.
