I have been scammed from OctaFX

I started to trade with
4500 and they promise to give me a 10% of what I deposit after that I started
trading but when I ask to withdraw my money they said you have no right to do
that and you have to sign a contract, then they said if you want your money now
you should sign the trading contract and when I just ask for my capital or my
starting fund the 4500$ they said okay just sign the trading contract to give
you your money back even that I do not want to trade with them anymore and I
just want the money that I deposit
