Unfair Credit Balance - LoRA Training Consumption Issue

I encountered a major issue with LoRA training costs. The estimated cost was 1,573.3, but I was actually charged 3,009. Because of this, my credit balance is now -938.62.

Currently, I am locked out of the platform's functions. Even though I have Stamina, I cannot join any Events to earn back the credits because of the negative balance. It is a "dead end" created by your system's inaccurate estimation (2x the expected cost).

Please fix my credit balance or allow me to use my Stamina to join Events so I can resolve this debt. This situation is extremely frustrating and feels like a system error.
