Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Greetings!
I'm Christine, I'll be happy to assist you. It seems like you've been charged twice for your subscription. Sorry to hear that. Just a friendly reminder, no one has access to your account in public forum for your security and privacy.
You may check the link below on how to request a refund:
And in case it didn't help, you will be needing to reach the MS Accounts & Billing Support to check your account.
Kindly open this link: https://support.microsoft.com/contactus/
Please sign in your account with the subscription, then click Microsoft 365 then choose Get Home Support. After that, please type Chat with an agent then hit enter. Scroll down and choose Contact Support, then please select MS 365 and Office then under Category, choose Billing and Account Profile question then hit next. You will see the chat option there.
Once you're connected to the Live Agent, please let them know about your issue so they could check your account and address your concern.
Thank you,
Christine L
