Disabled my trading buttons,when I was making big profits 📈.

I have joined quick trade last year june. My experience with them in terms if creating an account and funding was good. But there was a time where I was making big profits 📈. These guys disabled my trading buttons so that I don't make more money. I then called the support, they kept on telling me stories. From there, a guy answered and he shouted at me telling me that he owns the trading I must not speak as I wish. An hour they then activate my trading buttons. I was so disappointed that why when we make money they come with tricks. Mind you that time,I just made R 159 009. So I guess they don't treat you right when you make good profits. That brought my spirit down. I feel.like they operate like ****mers. When you loosing money,it's okay,but when you make money it's a problem. If they can treat me the same next time,where can i report them ? Because they deduct their money for a the course every month and sometimes I do loose money,why when I make money they become so greedy. Last I withdrew R100 000,they took 2 weeks to deposit my money but when I withdrew small money, same day j get it.
