If you purchased a Microsoft 365 subscription from a third-party retailer instead of the Microsoft Store, contact the third-party retailer directly to manage your subscription and billing.
Microsoft has limited access and visibility over subscriptions purchased through a third-party retailer.
Microsoft cannot cancel or help turn on or off recurring billing for subscriptions purchased through a third-party retailer.
All refund requests must go to the third-party retailer from whom you purchased the subscription because Microsoft did not receive that payment. (This also applies to Office Home and Business licenses.)
