How to retrieve Skpe credit it does not work. I am owed over Ten Gbp

Skype Credit can be reactivated if it became inactive after 180 days of no use.

1. Sign in to the reactivation page: Reactivate Credit
2. Select Reactivate Credit.
3. Allow up to 15 minutes for reactivation. A confirmation email is sent when it is complete.

To use or check the credit afterward:

1. Open the Skype Dial Pad at calling.web.skype.com.
2. Sign in with exactly the same Skype/Microsoft account that originally held the credit.
3. The balance appears next to the profile picture, and the Dial Pad can be used to place calls.

If the credit is not visible, check the purchase history:

1. Sign in to My Account.
2. In Account details, select Purchase history.

Important details:

• Skype Credit goes inactive after 180 days of no use.
• A reminder email is sent 7 days before it becomes inactive.
• In Teams Free, the Skype Dial Pad is available only when there is active Skype Credit. Updating Teams to the latest version is required to access the Dial Pad there.
• If using iPhone or iPad and the reactivation option or purchase page does not appear, clearing browser history and cookies and signing in again may help.

For direct support, use the Skype support contact page and select the issue that best matches the problem, especially payment, billing, or paid services.
