In firefly, I put in an image and asked for an alternate version, but it gave me back exactly what I put in and charged me 40 credits.

I put in a graphical treatment for a website, and I said show me a different treatment. I was using Nano Banana Pro and it gave me exactly what I put in without any changes, and charged me 40 credits. I don’t mind that it didn’t do anything, but do mind it charged me 40 credits for nothing. Could you return the credits please?
