Not sure what payment method you used, but you might try pursuing a claim with the payment company. Credit cards can usually do disputes within 6 months.

Is there a consumer protection agency in your country? Or a similar regulator?

Or the equivalent of small claims court?

If I were you, I'd never order anything off the internet without credit card chargeback protection. Especially from a random marketplace. Amazon's marketplace is full of counterfeits and such.
