What should I do if I receive such a text message when recharging the appstore?

This happened to me, too. You can recharge it in another way. Enter the App store, select recharge, select recharge amount after entering, then select UnionPay UnionPay as the payment method, enter the card number of any UnionPay bank card, and click Next in the upper right corner. It will prompt you that you have not filled in the form completely. Please enter your mobile phone number. Enter your mobile phone number reserved in the bank, click Next, and you will receive a verification code. Click Next after filling in the form, and the recharge will be completed, and the recharge amount will be received. Note: It must be the reserved bank card number. This payment method will be defaulted as soon as it is filled in, and will be recharged according to this payment method next time, and there will be no callback confirmation. Therefore, you must pay attention when choosing the amount.
