<prompt> Human: The lawsuit says that a data breech occurred sometime in 2013 and I am entitled to redress. The terms are that I provide must provide documentation supporting my loss. Its not even clear what company Vendini is and the form has a lot of legalese, as would be expected coming from lawyers. A little bit of research indicates that this is a ticketing agency used by movie theaters and some magazines. How do you provide proof if you arent even told what vendors were affected. Very confusing. The notification of the suit onlineThe company wont even admit any wrongdoing. Very frustrating.  <response>: ...If the suit is legit, feel free to contact legal counsel for EITHER plaintiff of defendant and ask what documentation they prefer. Generally, the amount of documentation is pretty minimal. Sometimes you just have to sign a form swearing, under penalty of perjury, that you were affected by whatever problem it was.
