leovegas free spins opened wrong slot and support says bonus already used

Used some free spins that popped up in my account, but picked the wrong slot because I was in a rush. Was supposed to use them on another game where I actually know the bonus round and have a way better shot at a big hit. Customer support says since I opened a spin and used them, that's it, they're gone. Tried explaining I didn't even get to pick the right slot, just clicked and realized after, but no luck.

Never had this happen before since I usually double check the T&Cs, but this was super unclear. Anyone else run into this? Feels kind of rough for something that wasn't spelled out better, especially when a quick mistake means your shot at a bonus just disappears. Has support ever reversed this kind of thing for anyone if you can show you didn't use the spins for a real session? Not sure if I should just take the loss or push it further. Anyone ever get spins refunded in a situation like this?
