Today, the customer service staff of the Credit Card Postal Savings Bank sold me a commemorative medallion commemorating the 70th anniversary of the world anti-fascist war, and an order has been formed. Under normal circumstances, it can be returned. Please communicate with each other in time. If it has not been delivered, ask the other party not to deliver the goods. If it has been delivered, it is generally supported to return it for seven days without reason. Consumers have the right to regret the three applications and five orders of the Ministry of Industry and Information Technology and any form of online shopping. Postal service cannot be duty-free, can it?
