Hi Indre. I'm Greg, a volunteer installation specialist and 8 year Windows MVP, here to help you.
Amazon backs their purchases so I would contact them via Contact Us Link here: https://www.amazon.com/gp/help/customer/contact...;
If they will not still refund it, contact the manufacturer as there is always a one year warranty during which time they must repair or replace the device. At most they can make you pay for shipping it one way.
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
