I THINK I HAVE BEEN SCAMMED

I came around an investment website and that i foolishly believed of their promises, i invested 500$ firstly they usually gave a 20% returns after the cycle which i withdrew successfully, then i invested one other 2,000 and i used to be suggested that there was a pump so i elevated my principal to 18Okay thereabout. When the cycle was complete, my workforce lead advised i held on a bit extra with an increased capital but i refused and asked for a withdrawal on the location, they say i pay a clearance levy of 1,700 which i did and then i was knowledgeable of a tax evasion coverage and that i wanted three,000 to make that filter out. after paying this i still couldnt get my belongings out of the web site.
