I was charged twice / my card was charged at checkout but the order was not placed, yet I received a successful charge notification from my bank. What should I do?

Please don't worry. Whether a credit card transaction succeeded or failed is determined by the order status on TutorABC Shop.

If a transaction fails or a duplicate charge occurs because of a connection interruption during payment or a failed capture, you may still receive a spending notification from your bank,

but TutorABC Shop will automatically cancel the card authorisation or refund the transaction.

The credit limit will be restored to your card in about 7–14 working days counting from the day after the transaction. If the refund and your credit card statement fall in different billing cycles, you will see the refunded amount on your next statement.
