I am using a credit card from Shenzhen Development Bank with a limit of 4,000. At the end of September, Shenzhen Development Bank sent me a text message saying that there was an activity to raise the limit to 5,000. The activity will last until October 31st.

You can call Ping An Bank’s national unified customer service hotline 95511, or you can go to the counter to make a statement, so that you will know more about each of your purchases and bank deductions. If there is anything unclear You can also ask the counter staff on the spot. If there is no SMS reminder, you can check to see if the number is wrong or the bank got you wrong. If everything is normal, but your money has been deducted but there is no SMS notification, you can call to complain.
