I'VE BEEN CHARGED MORE THAN US $14.00 FOR ESTA, WHY?
There are a number of third parties that have established websites that charge a fee for submitting your application on your behalf. If you have used one of these third party sites, we strongly suggest you use your application number to confirm with the official U.S. government site to ensure that your ESTA is in our system. We recommend you do this because we have no way of knowing if the information passed through the third party website to us is accurate. If it is not, you may have a problem when you arrive in the U.S.
For instructions on how to look up your ESTA, see the help topic "Checking Your ESTA Status".
CBP cannot refund the money you paid to a third party website, however if you think you have been victimized, contact your bank , credit/debit card company, or PayPal and request a refund of any amount over the US $14.00 required by the U.S. government by disputing the add-on charges on your statement.
