I feel for you, but as my wife pointed out I should just buy a phone from another company...
If there was an alternative I would have bought it, so patience is the only option ;-)

I particularly liked the line about order failed because of "incorrect payment details", I had to avoid laughing at them when they cracked that line.
I suppose they couldn't say order failed because of inane repeated auth's for 500 quid for no reason eventually triggering fraud rules...

Hang in there
