On the other hand you can't sue a company for losing your data in many EU companies. You can report them to whatever data protection agency your country has, and after an investigation they can fine, and/or, in more serious cases turn the matter over to the police for a criminal investigation.

The disadvantage of this is that the local data protection agencies haven't been handing out very big fines. Sometimes that's due to company law. In my country you'd fine the owning company, which in many cases will be a holding company. Since fine sizes are linked to revenue and a holding company typically has no revenue, this means fines are often ridicilously small.
