12Go charged me twice, how can I get a refund?

Submit a double-charge request through its support page and include screenshots showing both transactions, your booking ID, the last four digits of the card, and the date and amount of each charge.

12Go specifically requests this evidence to investigate duplicate charges.

Do not send your full card number, password, or other private financial information.

Once the duplicate charge is verified, request that the extra payment be refunded to your original payment method; 12Go says refunds are generally returned through the original payment method.

This is the information we have, but if you have more insights from your experience, please share in the comments.
