Am I getting scammed on THE ABANS TRADING APP?

I was approached on the nextdoor app and she private messaged me on there and told me to switch over to Whatsapp so that we can talk and then she'd began to try to be romantically engaged with me and show me how to trade and make more money. So I put in a thousand and I grew it to the number I have there on the screen now that I'm trying to withdraw 11 Grand they told me that the FSA got involved because of a previous card being wrong and now I have to pay back the whole sum. Is that a thing by the FSA?
