Hi @S'Learn_M
I’m sorry you’ve had to deal with this unexpected billing situation.
Please note that Microsoft Q&A is a public forum, so members and moderators cannot access your account, review charges, issue a refund, or arrange a supervisor escalation. Also, Copilot Pro and the Copilot benefits included with Microsoft 365 Family were not necessarily identical, since Copilot Pro provided more extensive AI usage beyond the standard AI-credit limits.
However, you can still ask Microsoft Billing Support to review the period of overlap and determine whether an exception or manual refund is possible. Sign in with the account that purchased Copilot Pro, open Microsoft Support, and choose Home Support > Ask our Support Assistant > Type "Talk to live chat agent" > Contact Support > Copilot > Chat with a support agent in your web browser. Ask the agent to review both subscriptions, the billing dates, and your payment history, and request escalation to a supervisor if necessary.
Refund approval is not guaranteed and depends on the purchase channel, timing, region, and account history. If Copilot Pro was purchased through Apple, Google Play, or another retailer, the refund request must be submitted to that provider instead
Thank you for your time and understanding
