I feel you, I can only imagine it must have been a stressful situation for you so far, a long ride indeed.
Good thing you called CS, at least now you know and good news that you'll have the nano soon š„°!
I'm sorry to hear about the PA order, maybe you could ask your local CA to try again? I suppose there is more stock coming soon, maybe it's worth a try. Or else you could ask online CS service to be placed on a waiting list as well. I'm on a waiting list for an item too. Don't know if that will work out at the end, we'll see.
I'm very happy you'll have the nano soon, after all your efforts you totally deserve it

. And I hope you can get the PA as well sooner or later.
