They keep boasting that they're "data-based and secure," but it's all fake. Now I can't even withdraw my principal! Last month, I saw some earnings in my account and thought I'd withdraw the principal first, but after submitting my application, there was no further news. Customer service initially said it would take 3-5 business days to arrive, but after waiting a week, there was no response. Sometimes they said my "bank card information doesn't match my identity information," and sometimes they said my "withdrawal application format is incorrect and I need to fill it out again." It's clear they're deliberately delaying my withdrawal because they don't want me to be able to withdraw my funds! What's even worse is that when I logged into my account again today, it was locked! I contacted customer service to ask why, and they said, "The system detected a risk in the account and temporarily froze it." They couldn't specify what the risk was.
