if you want to withdraw cash, you can recall the consumption situation before and after the consumption to see if it can help you remember. Another effective way is to look at your previous consumption records, whether there are similar consumption words, whether you received a consumption text message during the consumption, and we will first guide customers to recall when they need it when doing customer service. Then check whether there are similar merchants in the customer's recent consumption records for half a year or a year. If it doesn't work, register and inquire with other departments of the bank. Generally, the inquiry will be relatively troublesome. Wait patiently for 3-5 working days, or it may be found in 1-2 working days. I hope to help you.
