Read Linda Nee's blogs. I think they are posted here. link below.
She's in the US but her info helped me immensely. Not kidding. And I think it's more about what company vs what country you are in
They all have the same bottom line. Make money. And to do that they deny claims. And thet have a special hatred for CFS. I don't want to scare you but be scared. This is no joke. Read as much if her stuff that you can.
I will tell you this. It's about what you cannot do, not what you can do. The more you tell them what you can do, thinking that will help, it's just one more thing they Will use to deny you. They want to deny you.
I never talked to them on the phone. I faxed them and politely said I'm happy to answer your questions. Please send them in writing. Don't go on their website.
