I need contact UK number to speak to finance about payment

For a home Microsoft 365 payment issue, use Microsoft’s Get Help / Contact Support route to reach an account-and-billing agent; the published UK telephone numbers are listed as sales support, not as a dedicated finance department.

Contact Microsoft about the payment

1. Open Microsoft Support.
2. Sign in with the Microsoft account associated with the subscription.
3. Enter Microsoft 365 billing or payment issue and select Get Help.
4. If the suggested information does not resolve it, select Contact Support.
5. Choose Microsoft 365 and Office → Manage my subscription.
6. Select the available chat option or request a telephone callback, if offered.

This is Microsoft’s supported route for account and billing questions and routes the case to the appropriate support option.^1^

Published UK numbers

Microsoft lists these UK numbers under Microsoft sales support:

• 0800 026 0329
• 0344 800 6006
• From outside the UK: +44 800 026 0329 or +44 344 800 6006

These lines may redirect you, but Microsoft does not identify them as direct billing or finance numbers.^1^

If the payment is unrecognized, use Microsoft’s charge investigation process. If you believe the card details were compromised, contact your bank or payment provider to prevent further charges.^2^
