My card was charged twice by Quantum Evenity (quantumevenity.ai and ladfeeder.com) on the same day. I had to dispute it with my bank. Quantum Evenity (quantumevenity.ai and ladfeeder.com) then froze my account and said I had a negative balance because of the chargeback. They created the problem and then punished me for it.
