they won’t send you a verification code if you do not pay

Note that you must pay for it to use it, if you set the payment slider to 0, they will still show the next page for you to input a verification code, which they promised will be sended to your email address, but they won’t, because it is not free!

I tried three different email addresses from three different email provider (google gmail, microsoft outlook, and netease), and waited for over an hour, non of these addresses got any email from them.

If people must pay for it, you need to state it in all of your promotional contents.
