The customer applied for a weight-loss card and used it several times, and the effect was good. I suddenly want a refund. Can I get a refund?
If the customer's weight loss card is marked "no refund, no change", then the money cannot be refunded; If this clause is not marked, you can generally get a refund, but the customer can get a refund after using the weight loss card, and the merchant can deduct the discounts and gifts he enjoyed during the use, of course, the refund amount may be reduced.
