Just be patient and don't ever give up

Well done. I intend being equally persistent, and it's good to know they can add miles if they want to.
Do you mean you wrote to them online twice (automated online claims aren't possible for me in the usual way) and then wrote paper letters twice?
Which address did you send your letters to please? I can't find a physical address anywhere.
