Instant Gain Fx

Good afternoon, well, they made me invest 200,000 Colombian pesos in this investment account because I would earn 4 million pesos. Turns out that now to withdraw, I need a pin that costs 800,000, which I have to give to receive the pin to be able to withdraw the money. It seems to me like a scam because how is it possible that I deposited 200,000 and I have to give 800,000 more for a million pesos... it's not normal and I can't even withdraw my money or what's there already generated by the 200,000. And when I try to withdraw via PayPal, I get this notice that I have to ask for a code and that code costs me 800,000 pesos.
