^ I've done that too.
I understand your frustration but my advice is to hold off on quoting the T&C's and consumer law in the first instance and wait for a response from Executive Care - this is where decisions outside of the usual remit can be made. The trouble with quoting the law is it tends to create an antagonistic "us and them" scenario, they can also quote the law back at you in their favour and ultimately, if they won't back down, where do you go from there?
By all means after friendly negotiation you still have no joy then it's time to "bring out the big guns" and refer to consumer law and T&C's but hold that arsenal back for the time being.
Good luck;-)
