Has anyone ever got expired FC miles reinstated?

Had a quick search for this and the only relevant thread I could find (with my limited membership) was over 3 years old and locked. So apologies if I've missed this somewhere obvious and I suspect I know the answer to my question (and still won't like it much)...
But has anyone ever managed to get expired FC miles reinstated to their account? Or know of anyone else that has?
My Mum had over 40,000 that she carelessly allowed to expire in June last year, due in no small part to my Nan's increasing illness and everything else pretty much getting put on hold.
I've tried sending an email to customer services and boring them with how many of the extended family are FC members (8) and how many of them have the Virgin Atlantic MBNA credit-card (4) but to no avail.
What doesn't help is that my Mum did fly with Virgin within the previous 3 years and thought this was acceptable, but I think it was on a companion ticket or exclusively using some of my Dad's miles and so didn't qualify or extend the life of her membership.
So is there any final secret way that we can go about to try and get these miles reinstated or was the customer service agent really not fibbing when they said that 'to remain fair and consistent to all our members who are meeting the requirements set down in our terms and conditions, we will be unable to return these miles back to [her] account'?
Thanks in advance for your help
