Hi there, Tracy! This Marc. Thanks for reaching out.
Visit this link https://account.microsoft.com/services and from there, you should be able to see your active subscriptions and access options for billing support. If you have two separate Microsoft accounts, it's worth checking if the two charges are associated with different accounts, which might explain the double billing. Otherwise, Microsoft's billing support team will be able to investigate the duplicate charge and assist you with a refund or preventing future occurrences.
Let me know how it goes.
Best regards,
