To sue a service provider.

Hello, I need legal advice and legal action from a company AGAINST a service provider working in gaf. Here are the details: the amount he stole me was 350$. I want to recover this money. emphases on this legal action are based on: To contact that service provider's local police, credit scores will be lower for that individual, hence, it will be tougher for that indiviual to get good credit loans (mortgage, car loans, etc.) in the future. if that service provider is a company, it's credit score (letter of credit) will definitely be affected, hence, it will be more difficult for that company to do business with anyone in the future. please only bid if you have experiences in these cases. Details about the name of that service provider will be given in PM.
