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
