This problem has been targeted by banks, and even the right to redeem points has been frozen, which is already very serious. I personally suggest a solution:

1, standardize the use of cards, and do not violate the rules.

2. Provide invoices and receipts as required. If it is real consumption, there are relevant invoices and documents, which can be provided as required.

3, the receipt can be reissued, and the POS machine can complete it; There is no invoice to make up, such as Huaqiang North subway station in Shenzhen.

4. Communicate with customer service, because I accidentally lost the invoice/receipt.

I didn't ask for an invoice because there was a discount on spending money.

6. Tear it up. The bank didn't fulfill its obligation to inform in advance.

Users need to keep consumption vouchers and invoices for investigation after spending with their cards. At this point, most banks have not fulfilled their obligation to inform in advance. Let's look through the credit card authorization agreements and regulations of various banks to see if there is such an eye-catching reminder: let users pay attention to keeping the consumption vouchers after each consumption. Some banks will cash in installments and borrow cash in advance to remind users that they need to keep consumption vouchers, invoices and other materials, but they do not indicate how long they need to keep them.
