Is it true to call me and say that platform partners have credit lines?

No, credit extension refers to credit card cash transaction (that is, cash withdrawal) business. Banks need to pay a certain amount of cash within the credit card limit of customers and transfer it to the credit card limit. Adding credit refers to the credit card limit that increases the loan amount. Calling and saying that the platform partner has an additional credit line is not true. If the platform can find an additional credit line, there will generally be SMS notification.
