Avatrade investment

I was on the Avatrade Telegram when they advised me to invest 250$I will get 8700$ in return after 48hours, when it is time for me to get my profit they said I must pay 800$ for tex so that I can get my profit, then I payed that 800$ thereafter they send me email, on that email they said I must pay 700$ for ibpc so that I can get my profit, I then told them I can't pay that money unless they pay me my profit first.they then advise me to pay 450$them they will pay the rest of the money.i keep telling them that I won't pay.the person I was communicating with is Web lock,this is a very good ****, they know that we like to invest and they take advantage of us.
