I called a few of the numbers given above, and was given these:
01332 867 000 - This is their old number, before they re-located so no good.
01158 507 900 - Not sure what this one is, but they happily redirect to customer relations. The lady in customer relations mentioned it's their HR or PA number or something, I dunno lol
01332 263 303 - This is Derby Station's phone number.
Hope the above is useful for someone
