If Black Cat complains that the loan app cannot log in to repay, it means that the loan app may be subject to supervision and investigation by the national regulatory authorities. You can call the loan company to ask how to repay. Because the loan has occurred, it must be repaid. If the interest rate of the loan exceeds the national regulations, you can complain to the relevant department and repay the loan according to the national regulations.

1. Black Cat Complaint Platform

It is a consumer service platform under Sina. Through Black Cat Complaint, consumers can give feedback on various problems encountered during the consumption process at any time. Relying on a massive enterprise database and influential experts in various fields, consumers can receive quick feedback and professional guidance on their needs, thereby building a communication bridge between enterprises and consumers. Currently, the platform supports Weibo account, mobile phone number, and WeChat login modes. After logging in, you can initiate a complaint directly on the homepage. The progress of initiating a complaint can be checked at any time through the personal center. Black Cat Complaints currently only accepts complaints related to consumer disputes, so do not submit complaints that have nothing to do with consumption and be sure to ensure the authenticity of the complaints.

2. Black Cat Complaint Resolution

1. If the status of the complaint is "Processing", it means that the Black Cat platform has notified the corresponding merchant of your complaint. Due to the large volume of complaints, it may take some time for the merchant to handle the complaints. Please wait. If there are any questions, you can supplement the complaint in its original form.

2. If the status of the complaint form is "to be assigned", it means that Black Cat is making every effort to get in touch with the merchant. Please wait.

3. If the status of the complaint form is "Failed", it means that your complaint was returned due to various reasons. Please revise your complaint and submit it again. The reason for failure will be stated on the original complaint form. Submitting a complaint form that lacks the most basic transaction-related information may also result in the complaint form being "returned." The more detailed the relevant evidence, the more conducive it is for merchants to quickly resolve customer complaints.

To sum up, if you encounter illegal loans, you can complain through the Black Cat Complaint Platform and complain to the relevant departments to reasonably fight for your own interests.
