withdrawal rejected for no reason and no assist

That’s good when I using FxPro, the platform, spread all nice. But when I try to request withdrawal, they keep rejecting without giving any reason. I email to the support email also no response more than 3 days, they keep saying I lack some documents, and don’t tell me what’s it. Even though I submitted phone ownership proof, they also don’t try to call me for verification to let me request withdrawal. I can’t find any one assistance me in live chat, keep telling me to wait.
