Except.... while on the phone to the call centre, it resurrected itself. I just know the Cylons are behind this somehow....
EDIT : It died. AGAIN.
(Notes to self, cos I'll lose the piece of paper they're written on otherwise : call centre number - 0800 587 1102, incident number 1067875001. Plus, I hate having to spell my whole name over the phone each and every time. K for kilo, O for oscar....)
June 10th update
Spoke to lady, reported fault. New reference number : 106 966 88 83. UPS courier will be coming in next 5 days to collect 360, which needs hard drive stripped off it.
New reference number : 107 149 3654. On the occasion of having to ring them up on 0800 587 1102 again, to ask them how to change the payment options on my X-Box Live. As in they'd canceled my X-Live because the original bank account the debit was coming out of was closed, but I couldn't get into Account Management to change my details because they'd canceled my X-Live. Catch-22 at its finest.
