Hi, @AeronaBlack.

We understand that you got an unrecognized charge even though you don't have a Roku account.
In this case, it would be best to reach out to our Account-Billing team, as they can further assist you with this. Visit our Account and Billing Support page and choose the "Account, payments & subscriptions" category. There should be an option to talk to one of our live representatives.
