When did you confirm receiving the online hot pot coupon, when did you eat it or when did you receive the electronic coupon message?

When you receive the short message, electronic certificate receives it successfully. To be on the safe side, you can go to the restaurant you ordered first and go to the bar to explain that you ordered the e-ticket online. The bar staff will ask you to provide the electronic coupon order number or the electronic coupon verification code and password. After telling the service staff, the bar staff will tell you that the e-voucher is valid and can be used, and it is not too late for you to confirm the receipt. If it is a group purchase meal voucher, you don't need to confirm the receipt, and you can use it directly after receiving the e-voucher SMS after payment.
