I received a short message today, saying that China Construction Bank was overdrawn. ..

Typical scam message, never calling back. When you return to the customer service over there, you need your bank card number and password to help you check the balance. In fact, if you check the bank, you only need the card number, not the password.

And the bank won't send text messages to your mobile phone. Short messages from banks often carry your name. If your card is overdrawn, someone else's bank will send you a real-name message if there is any information about you.

A current all-in-one account cannot be overdrawn.

The customer service telephone number of China Construction Bank is 95533.

If in doubt, please call customer service. Or report this number.
