Ask them for a Fair Use Agreement (as Deveant mentioned) and if they can't provide you with one, record the name and employee number of the person that gave you the information. If they don't have a Fair Use Agreement, they can't shut you down without a valid reason (and using what you paid for isn't one). With the recorded info, you will have material to fight them back and to tell them to F*ck off.
This is the way I dealt with a few companies and it usually work because you keep track of the info you receive (and you can magically misplace the recordings of the info that doesn't please you)
