It is very possible to buy dog meat by hanging sheep's head. Who knows if that gold ring is a blessing in disguise? In case there is something wrong with your ring, for example, it is fake, for example, the gold content is not enough, for example, because your invoice can't be returned to him.

The invoice is equivalent to the evidence that you bought this ring in Liu Fu. There is no seal or logo of Liu Fu on the invoice. Your invoice can be said to be useless and invalid. You didn't upload your invoice photo, so I can't tell you the company on the invoice, but one thing, Liu Fu is not written on the invoice. I suggest you go back and ask her to reissue the invoice.
