This is very difficult. Unless there is a quality problem, the merchant will not be willing to suffer this loss. After all, you have been carrying it for almost a year, and even if you recycle it, the price will definitely be crushed. Generally, recycling will begin after 3 years, but it is very expensive for you to take back the test certificate. Merchants are just a gimmick under the banner of recycling. Take it with you and earn more money for a better and bigger one.
