Collect money. Why can't the system log in?

Looking for customer service to provide relevant certificates to handle login failed. Firstly, the following points are excluded: 1. Whether the account number and password are correct. 2. Do you need contacts? Check whether the network is normal. 3. Unable to login the prompt. 4. You can contact the relevant personnel of the cashier software being used. Collect money, maliciously freeze the merchant's collection, and don't even say the reason or complaint. Are all the money earned by our merchants collected and remitted? Let me complain directly and give me a lot of things that I need to provide. I don't know what I need to provide, and I am very confused. I'm just trying to freeze the money of the merchants.
