I Discovered Unauthorized Blizzard Entertainment Charges on My Card

This morning, I was shocked to discover four transactions on my card from a company called Blizzard Entertainment, a name I’ve never heard of before. I have no knowledge or connection to these purchases, and I’m completely bewildered by this situation. I urgently need assistance to resolve this matter and stop any further unauthorized charges. I expect a swift resolution and a full investigation into how these transactions occurred without my consent.
