Paid Wrong Currency

HI there, we are using this plugin and recently a customer in EURO country made a payment though in EURO rather than AUD.

We do display prices in EURO using this plugin though the issue is that the payment came through in Euro dollars instead of AUD and the result is that rather than the customer paying the dollar conversion cost which is normally included in the total, we had to pay the conversion rate cost as an addition al fee.

Apparently the customer was provided an option which dictated this result so they chose the cheaper option.

We use Stripe and spoke to them about this, they confirmed that they do not do this as the option to choose currently type at the checkout related to a currency conversion plugin which is this one.

Can you let us know if you need more information, is there an option in this plugin that allows us to atop this from happening?
