I often can't log into my account, it says the username or password is incorrect, but they are not. I even changed my password via SMS, but still couldn't log in. I added a manager from the official website on WeChat, we chatted briefly and then they stopped replying; further inquiries were also ignored. Previously, I had several accounts under this login, but when I tried to access them six months later, all accounts had disappeared even though the username and password were correct. Recently, I couldn't log in at all with these credentials. Accessing their official website is very unstable, sometimes I can't get through at all. Even if there is money in your account, you can't log in, you have no way to withdraw it.
