No, you have exceeded the after-sales period, unless you contact the merchant to negotiate and the merchant agrees to your request, you can get a refund. If they don’t agree, you can’t get a refund. Many products are time-sensitive, and some products may be from Tsinghua University. In this case, the merchant will not refund you, after all, it’s been too long. Another thing is that if you return the product that is not sold, they will also hold back their inventory. There is no need to return it as soon as possible within the after-sales period to avoid unnecessary losses caused by not being able to return it after the after-sales period.
