Do not withdraw after earning profit

I received a bonus of $100 on the onepro platform on February 22, the official website https://www.oneproglobal.com/ The platform stipulates that the bonus requires trading at least 10 lots, each position is not less than 3 minutes, and the validity period is 2 months. I completed a trading volume of 10.7 lots on March 10, and each position was held for more than 4 minutes, with a total profit of $155. But on March 11, when I asked for the bonus to be transferred to the balance and withdraw the fund, the platform actually said that my holding time was less than 3 minutes. I negotiated with the platform many times and sent a screenshot of each order to the platform, which clearly showed trading volume of 10 lots is more than 4 minutes, but the platform still ignores and does not reply. Therefore, this kind of platform is blatantly bullshit with nonsense, and it does not withdraw.
