This may be because Bank of Communications has used your local picc account as a blacklist account. I have encountered situations where Industrial Bank cards were restricted from using cards at insurance companies. The main possibility is that the single purchase of the insurance company is large and there are too many credit card transactions. Some insurance company insiders often take advantage of the convenience of paying premiums by swiping cards on behalf of customers to cash out, etc. Therefore, most banks treat insurance company purchases as non-points purchases. , and even restrict the consumption of our bank cards with certain insurance companies.
