⚖️ Seller Warranty & Marketplace Dispute Conciliation

If, after attempting basic solutions (battery replacement, cleaning), the calculator exhibits persistent issues such as a permanently blank display, keys that never work, or clear signs of a manufacturing defect (loose components, poor internal finish), contact support under the seller's warranty and marketplace return policy. These indicate a manufacturing defect that cannot be resolved by the consumer.
