Tradefills scammer Alert

Good day my name is Nawaaz and I am a day trader, I have been with Tradefills broker for the past 3 months and our team as well. We are based in Sout Africa and have a group of around 300 traders, we all have been scammed by Tradefills as they have blocked all our accounts and refused to pay us our withdrawals.
Please if you read this do not trust Tradefills because as soon as you become profitable they will stop sending your withdrawals

If anyone has a way to report them in which we can take legal action against them please let me know as we have backing of around 300 members who has been scammed by this broker
