It'll be better if you'll provide the email that has been sent to you by the HitBtc team saying that they will not unlock your account after doing all the demands they asked from you. If your story is true, then it is not fair and they should be punished in a way it is fair as well. I don't use Hitbtc since they also locked my account (luckily I only have a few bucks their)

Whenever I log in, it'll say that it needs the Code from 2FA security, and then I asked for their help to unlock my account by disabling the 2FA security and they said my account has no 2FA. I don't know what to believe anymore. They need to improve their customer service.
