The charge is a recurring payment

If you have previously purchased Skype Credit, you may have Auto recharge set up on your account. Auto recharge automatically tops up your Skype Credit when it falls below a certain amount, to ensure you never run out of Skype Credit.If you no longer wish to top up your Skype Credit, you can cancel Auto recharge.If you have signed up for a subscription, the subscription is renewed automatically at the end of the initial period, and the recurring payment is made with the payment method you used to sign up. To stop the recurring payments, you need to cancel your subscription.
