I got an invoice or a charge and I don't know which account it is
Contact our support with the invoice number, the PayPal email you paid with, or the last 4 digits of the card with the date and amount of the charge. We tell you what the charge is and which Flat account it belongs to. If you paid for someone else, such as a child, we can cancel or refund it once we have traced the charge.
