Man of Honour
I had the same issue, the web page was stuck on processing for me. I refreshed the page and got a confirmation instantly as well as an email.
It was stuck for over 15 minutes and a refresh lost it.
What did you use as proof of purchase ?
My paypal email uploaded as a pdf.
I had the same problem, I claimed just before leaving work and it hung on the "processing page" after submitting PoP. Thought I'd try again at home and it said the IMEI number had been used so no idea if it has worked properly or not and I have no confirmation as yet.
I tried again today but got the same with the IMEI. If no confirmation email arrives by Wednesday I will contact them.
