I made a test reservation on Avis.com for GLA airport. On the final confirmation page under terms & conditions, here is what it said under Driver's License Requirements:
Do I need to bring my driving license with me?
International Driving Permit is required unless driver has a license issued within the EU. US, Canadian, Australian & New Zealand licenses are accepted (International driving permit not required for renters with a US, Canadian, Australian or New Zealand license).

It seems pretty clear. Avis is under no obligation to refund your money, but you can try disputing the charge with your credit card company if you want. Just keep in mind that you may end up on the
Do Not Rent list for Avis and Budget.
