After Taobao bought something and sent it back for replacement, the owner ignored me.

Try to contact the owner through Want Want. If the owner doesn't reply, you can try to find the owner by calling the sender's phone number or the return recipient's phone number given by the seller.

If the owner has been ignoring and has not received the returned products, then he must apply for a full refund. If the owner does not operate the system, it will be refunded by default. If the owner refuses, you can apply for Taobao customer service intervention; If you have completed the operation of confirming receipt, you can apply for after-sales refund. The method is the same as above, and you can also complain about the behavior of the owner after the operation is completed.
