Unauthorized Mobile Payment Charges by PUBG

I was shocked to find out that PUBG had charged my credit card without my permission for in-game purchases. I didn't make these mobile payments, and I'd like to get my money back for them. Unfortunately, I haven't been able to get in touch with PUBG's customer service. I haven't been able to get in touch with a person, and the customer service options haven't helped. Because of this, I'm reaching out to other readers who may have had a similar problem and may know how to solve it. The fact that PUBG charged me without my permission has caused me a lot of stress and sadness. I want to make it clear that I have not given permission for any mobile payment charges, so these charges are not valid. I'm determined to get a refund for these unauthorized charges, so I'm asking the community to help me get in touch with PUBG customer service or give me advice on how to fix this problem. I'd be grateful for any help that can be given in this matter.
