There is something wrong with the software itself, and there is something wrong with the way the bank card is bound.

1, the problem of refueling treasure itself: because the version of refueling treasure app is too low, the system is unstable or there are other technical failures, it is impossible to unbind the bank card. You can try to update the version of fuel treasure app or reinstall it.

2. There is something wrong with the bank card binding method: because the user did not fill in the bank card information correctly when binding the bank card, or there is something wrong with the bound bank card itself. You can check whether the bank card information filled in is correct, or contact Jiayoubao app customer service to help solve it.
