If your are an existing customer and have placed an order, then changing the billing currency for your account is not possible. However, new customers can make such a request prior to placing their first order. To make sure you're set up with the right currency, you'll need to create a new account and then we can transfer all services from your existing account. The product price will be adjusted accordingly for the new account's currency.
Currently, taking advantage of this process does not incur any extra cost.
