I actually received mine today and applied to my account, just over 2 weeks.I had recently (2 weeks ago) bought the phone but only received it a couple days ago. Have raised the claim and got the confirmation that the voucher would be emailed in 30 days. Now to wait I guess.
On a different note, has anyone bought direct from them with the trade in option ? I have not received any information as to how/where to send my old phone. I read somewhere that you are supposed to send it back in 7 days.
