Scammed by 24Option, OptionsXO, Plus Option, Xtrade，etc

Hi my name is Sithabiso Mhlakoana from South Africa. In 2017 I was scammed by different brokers of a lot of money totalling to more than $8000. Most of the funds were paid online through my bank card. I do have proof of payments for all transactions including some of our conversations with them as I was trying to demand my money back. In some instances I was making some profits after trading, but when I wanted to make withdrawals they would refuse to process them until they block any means
