Unable to withdraw

I deposit more than 55,000 on the indodax website. Last week I went to withdraw and they rejected me on the grounds of system upgrades. The second withdrawal said that I could not withdraw cash on weekends. I went to withdraw cash on Monday and said that I violated the rules and froze me. Ask me to deposit another 20,000 to unblock it, and let me deal with it within 24 hours, otherwise I won’t handle the unblocking business for me, and now I can’t even log in to the website.
