The gold invoice I bought for Chow Tai Fook is gone, so I can exchange it. If you want to exchange gold jewelry, you can go to Chow Tai Fook's store and do not need a receipt. You can also have a mobile payment voucher. If it is cash, you can take jewelry to the counter for consultation. They are all in the file.

Matters needing attention in jewelry trading

If the jewelry store can find the invoice stub when the consumer first bought the diamond ring, it can be treated as a lost invoice. The corresponding consumers also have to pay the handling fee for reissued invoices. If there is no invoice and voucher, the jewelry store can't find the invoice stub when the consumer first bought the diamond ring. If the consumer wants to exchange it, the jewelry store can evaluate it, and the consumer can exchange it after making up the difference.

You can't prove it without a receipt. You bought it here. Keep an account. If you know the staff inside, maybe you can find a way to help coordinate. If the size is not suitable, who sold it that day should still be remembered, and it may cost them a certain fee to exchange it. You can't help it if you don't like the style. The invoice is proof that you have made a purchase in this store. If there is no merchant, you have the right to refuse to serve you.
