Easyjet flight - can you remove hold luggage that you've booked?

[DistantConstellation]

Booked an easyjet flight to France a few months ago. Had no idea how much luggage we'd need, so booked 2x 23kg hold cases just in case, as well as the 'underseat' ones you're allowed by default. Can't even remember how much they charged as they haven't broken it down anywhere in any of the booking emails but think it was about £65 each suitcase.

We have practise-packed and should be fine with one so want to get a refund for the second case - is this possible? Definitely can't see a way to do it online - only to add hold baggage or change seats etc. Couldn't even find a way of adding a large cabin bag if I wanted to.

Anyone know if it's possible or if it's non-refundable?

Unfortunately not according to the t’s and c’s here https://www.easyjet.com/en/help/booking-and-check-in/managing-your-booking

Ah bugger. I don't think that was in any email but I guess they just link to the Ts&Cs. Definitely wasn't made clear at the time of booking - in fact it was really confusing to book as initially the only reference to what luggage you want was tied to what kind of seat you want.

What a waste of money :(
