Firefly not doing anything

Hi, this Firefly AI isn’t worth anything. I have 4000 credits on my account. Today I lost 600 credits on nothing. After 5 attempts to make this clip I uploaded somewhat modified, all 5 attempts were exactly the same. I prompted it clearly. Several times. After 5 attempts it gave me exactly the same thing as at 1st attempt. So, who’s fooling who here?! So, I lost my credits. Adobe should refund those credits because I got nothing out of it.
