No, it’s not at all legal for the company to do this. Reply and remind them they have one calendar month to comply from the date of your original request, otherwise you will make a complaint to which ever information regulator is correct for the juridiction they’re operating in.

For now, I do not want to announce the name of this company publicly.

If they won’t want to resolve it friendly, then I will do so.

Why not? That’s so weird…
Think of the poor corporation! If they get punished for their illegal buisness practices, it’ll hurt the economy and people will be less inclined to start a small buisness. Didn’t you study piss down economics?
