Easy Jet flight and payment confirmed, but payment was actually declined

I booked an Easy Jet flight last week (27th July) and everything seemed to go through okay. I received a flight confirmation Email and can view the booking on my account.

I only realised today that the payment was declined because I put in the security code wrong.

I've checked and the payment definitely didn't go through, yet I haven't received any notification from them. Nothing pops up when I view the booking like "payment pending". I even requested a payment confirmation Email and it came through with no issues.

I'm wondering if I should just wait and see if they get in touch and see if they let me board anyway. I still have the booking confirmation so it seems like I might have unintentionally bagged a free flight.
