VAT tax was applied to my order when I have a valid VAT ID. How can I obtain a refund for the VAT amount of my payment?

In case you want your VAT amount to be refunded you will have to contact our payment provider 2CheckOut.
Here is how to do it:

1. Access My Chaos and sign in with your username and password.

2. Click on Billing -> Invoices.

3. Click on the three-dotted button beside each invoice and then on Request a Change. A Compose Email window will open where you can request your invoice change. 

In addition, you can add your VAT number for your future purchases in the Billing -> Billing Information section.
