For a Mac, both Microsoft 365 subscriptions and Office 2021 (one-time purchase) can be installed, so switching to a Microsoft 365 subscription is a valid option for Word on macOS.
For the existing purchase and refund request, direct contact with Microsoft Support is required; community forums and automated help cannot process refunds or access billing details.
To request help with the purchase and ask for a refund:
- Go to the Microsoft Store purchase help page and select Get help: this will guide through self-help and then offer chat or a call-back from support if needed.
- If more help is needed, use the regional phone numbers listed under Customer service phone numbers for home users and choose the country/region to get a phone number to speak with a person.
To contact Microsoft support specifically for Microsoft 365/Office and discuss switching to a subscription:
- Go to the Microsoft Office Support home page and use Contact Us at the bottom of the page.
- When prompted, choose the Microsoft 365 & Office (or similar) product category and then a billing/subscription category such as Manage my subscription.
- Proceed to select Chat with a support agent or a Call me back option where available.
For Microsoft 365 subscription questions and technical support (including confirming that Microsoft 365 for Mac will work on the device):
- Use the Microsoft 365 Customer Service and Support options for home products. With a Microsoft 365 Personal/Family/Basic/Premium subscription, chat or call-back support is available.
- If already subscribed or once subscribed, support can help confirm compatibility and assist with installation and activation.
If the goal is to cancel a Microsoft 365 subscription later and request a refund (for example, if it does not meet needs), follow the refund guidance for Microsoft subscriptions:
- Use the Microsoft subscription refund article to review eligibility and steps.
- If self-service cancellation and refund options do not appear, select Contact Support in that article to reach an agent, then explain that the product could not be used and that a switch to Microsoft 365 is desired.
For any general Windows/Office download, install, activation, or billing issues as a home user, the Get Help entry point is the primary way to reach a human agent; it can route to chat or call-back support after describing the problem.
