Hello, the online loan situation you encountered is very simple and fast, and you don't need the guarantor's signature and property mortgage. After the application, it was quickly passed. Then the system shows that the loan has entered the APP wallet, but your bank card has not entered the account. The customer service of the platform said that your bank card number was filled in incorrectly, which led to the failure of payment. You need technical treatment to modify the card number. However, you need to pay a handling fee to modify the bank card, and the customer service will inform you that the handling fee will be credited to your bank card together with the loan. If you unilaterally terminate the loan, the other party will tell you that the contract has come into effect, and you will not only have to repay the loan, but also have other serious legal consequences. If this is the case, it is recommended to contact a lawyer directly.
