I maxed out my credit card on gacha and got no SSR units

The banner said 0.6% SSR rate. I am a mathematician. I understood the odds. I respected the odds. I then spent $800 trying to beat the odds. I got 47 duplicate SR units and one SSR I already had. The event ends tomorrow. I have $12 left. My credit card limit was $800. It is now $0. The character I wanted is still not mine. She is fictional. I know this. Please help me pay my minimum payment. 🙏
