Sorry to hear about the unrecognized charges on your card. For account & billing concerns, it may be more effective to get help from our Billing team. You can also contact them here: then choose 'Account, payments & subscription'. They are the best ones to help you out with that matter.
I'm going to mark this post as solved as no troubleshooting is needed in this matter but I hope the information above is helpful, and please follow up here if you find any other solution so that others could benefit.
