sister bought concert tickets using my card

Hello! Just looking for some advises here.

My sister (16 years old) bought 3 VVIP A tickets for kpop concert. They are worth 18,500 each. The thing is, walang permission ko. She used my credit card and phone for OTP while I was bathing my cats last Saturday. Nalaman ko lang nung macheck ko BPI CC ko, may malaking bawas sa CL. She hasn’t claimed the tickets yet, and sobrang pinagalitan ko.

Will I be able to dispute or cancel these tickets? Or the only option is to find buyers? Sobrang nakakastress :(
