I'm just completely dumbfounded. (3 images total)

From 6 AM to 6:30 AM. I put down my phone and was washing the dishes my boyfriend used after eating. However, while I was organizing my bank account's spending history, I noticed a payment from an app I never downloaded? The title said something like 'Do you need a refund?'... I guess this is how new scammers operate these days? This is why I always withdraw my salary in cash immediately... I forgot to do it this time, and this happened... What should I do in this situation? ㅠ I'm worried sending an email will expose my personal info again... ㅠ (It's enough that my accounts on TVING and Google were already hacked... ㅠㅜ) After dealing with that kid's mom, now I'm getting ripped off by a scammer too... My life is great. Yeah...
