I did ask my friendly customer relations person at Norwich Union whether they would give me the 7 day free insurance on another car purchase, even if not bought through ebay, given that, for whatever reason, I had not received it on my mini purchase, and she has set it up. She has primed someone at another office to expect my call.
I am delighted with this outcome and want everyone reading this to know how grateful I am to Norwich Union and to this lady in particular for the way my complaint has been handled. I'd like to name her, but out of respect for her privacy, I shouldn't. After all, for the same reasons, I don't even write in my own name.
But you know who you are so, Thank YOU.
