Discovering a crack in the dome of your brand-new toy crane machine is frustrating. Immediate and correct action is key to resolving this issue smoothly. First, do not dispose of any packaging. Carefully document the damage by taking clear, well-lit photographs of the crack from multiple angles. Also, photograph the original shipping box and any internal packaging that shows signs of mishandling. These images are crucial evidence.

Next, locate your order information, including the invoice, receipt, or order confirmation email. With your photos and order details ready, promptly contact the seller or manufacturer's customer service. Clearly explain the situation, state that the item arrived damaged, and provide your documentation. Most reputable companies have policies for damaged goods and will offer a solution, such as sending a replacement dome, providing a partial refund, or organizing a full exchange. If the seller is unresponsive, you may need to escalate the issue through the platform you purchased from (like Amazon or eBay) or your payment provider (like PayPal or your credit card company), as they often offer buyer protection for damaged items. While waiting for a resolution, avoid using the machine if the crack is severe, as it could worsen or pose a safety risk with small parts.
