you know what, you screwed yourself.
first thing is that the MUTRK.com does not take money from anyone. They are totally free websites and I am a earning a good amount of money every month by it. I did a free registration and paid nothing.
The one who you paid money was not mturk but some people who say they will give you jobs. In fact they dont give you jobs but just advice you. If you read their terms and condition carefully you can see this.
