I cancelled a redemption as I found a better redemption option. Rather than trying to change the original ticket, I just booked the better option as I was afraid availability would go and the taxes/fees were less than 20 euros in any case.

I was due a refund of about 2 euros after the 20 euros kept by A3, however after 3 weeks no refund has appeared. As calling A3 is rather aggravating for me, I thought I would just rant here and forego the 2 euros.
