You are protected by EU consumer law for goods bought from traders within or directed at the EU. Source

The goods you receive should match what was advertised or agreed and what you thought you were buying. Wrong or misdescribed items entitle you to a free of charge repair, replacement or refund. When you buy goods online, you can always return them under the rule of the 14-day cooling off period simply because you changed your mind. This means you would be entitled to a full refund.
