Alibaba provides after-sales protection for ordinary orders after the transaction is completed, but the specific after-sales service content and processing methods depend on the seller's after-sales policy. Generally speaking, if the goods received by the buyer have quality problems or do not match the seller's description, they can obtain after-sales service by applying for a refund, exchange or repair. In addition, Alibaba also provides consumer protection services, including Alipay guaranteed transactions, quality deposits, etc., to provide buyers with a safer shopping environment.
