"All the scripts supplied by the party for these calls are compliant with data protection and information law."
Got be to honest, I would have questioned the individual on what they thought that sentence actually means.
I regularly get into discussion with telephone sales / marketing / call centre people. Whenever they say that xyz is for "data protection purposes", I ask them which clause of the Data Protection Act 1998 requires that they ask me for that information. I've never yet had a single person that even understands the question; they are trained to ask their question, but have little to no understanding of the actual purpose of the Act, and what it relates to in terms of their particular job function.
In many cases, it's clear that the companies concerned are just ticking boxes, and know that they are required to do *something* for Data Protection; but I have to say I am not convinced that they are always adhering to the complete legal requirements.
