You will have to give us more information than " Someone cheated me ". What happened? How much money are we talking about here that was lost? It may be hard to take legal action without a contract of some sort.
Yeah, we're going to have to know a little bit more than that. Have you used computers and the internet to make money for a long time? If you haven't, you need to get familiar with your local contract laws. What happened?
Well $20 minimum for any LEGAL suits, but that doesn't mean you can't track them down and get it with some good manual labor and coordinated punches
Yes. If you are cheated out of $20 then it is not worth taking any legal action. It all depends on the amount as whether or not worth taking legal matter.
