I bought something on Taobao, but the seller sent it to the wrong address. The seller said he was in contact, but there has been no news. Can I refuse the visa when the courier arrives?

if the goods are unpacked because the seller sent them to the wrong place, or because the goods were sent to the wrong place, the time is delayed and they are no longer needed, then the visa can be refused!

But usually, unless the goods are unpacked, it is best not to refuse the visa, because it is not easy for the seller to make some money, and if you refuse the visa, he will have to pay the courier fee.
