First of all, we don't know whether the store has relevant qualifications and business licenses. If you really want to return the card, go to them. If they don't return it, let them take out their business licenses, or affix their seals, official seals or financial seals on the receipts. With the seal, you can know the company name, at least you can find the root cause.

Of course, you must have a good attitude when you say you want to return your card or stamp your business license. If they are particularly uncooperative or have a bad attitude, I suggest you call the consumer rights hotline 123 15, which can at least guarantee your legitimate rights and interests.

If you don't want to make a summary, spend it as soon as possible, lest the building be empty after a long time. Such examples are not uncommon.
