I want to sue Internet Company

Well here\'s the thing. One company claims on their web this: "Natural traffic is type-in traffic. Also traffic that is generated through clicking a link displayed on a search engine is considered natural traffic".

I provided for their sponsor program exactly that, and they canceled my account under this accusations:

Audit of your domains traffic was not converting to sales for our advertising partner\'s sponsors and per our agreement with them we could not accept it. our quality management team found that the traffic coming to your domain names was not natural (type in or related to search engine placement or past development).

Since they canceled my account and i didn\'t get paid they made me broke, and in very tough position (search engine placement bill) All provided traffic came from the search engine placement coming from established online company.

Do I have case against them for this? They are well known company. Thanks in advance for Your help
