Received a text message that Ping An Bank's credit card was abnormally frozen.

I think the reasons for the abnormal freezing of Ping An Bank's credit card may be:

1. Insufficient credit limit: the bank may temporarily freeze the card to prevent arrears.

2. Abnormal account: there is abnormal transaction in the account, which is suspected of fraud.

3. Overdue repayment: failure to repay on time or insufficient repayment amount.

4. Security verification: too many password errors, etc.

5. Banking system failure: The banking system occasionally fails.
