Wrong item delivered

I ordered these stairs and ramps for my boys' Christmas present so they could have more creativity with their building, but the wrong product was delivered. Instead, I was sent Shape Mags Mega Stabilizer Set. I paid a hefty $30 for shipping and import taxes, effectively doubling the cost of this item, and I do not want to have to be responsible for paying the return shipping for the store's mistake. I even tried to refuse delivery, telling DHL that it was the incorrect product (it was not shipped in a brown box or any outer layer box), but DHL said I would have to file a claim with the seller. I am hoping the seller will make this right. Right now when I try to file for a return/exchange, I get this message from Crystal Deals, the store: "We'll refund up to $15.00 in return shipping costs once we receive the item. Print the return shipping label anytime from Your Orders or your email." However, $15 won't come close to covering the shipping from the Czech Republic to the USA. Please fix the mistake without punishing the customer, Crystal Deals!
