I bought a 390 Nitro last month and kept my Hitman voucher unused.
I tried to use it today, but when I entered the unique voucher code into 'www.amdrewards.com' it said I also have to provide the proof of purchase..
So I did it. I attached a photocopy of the voucher and the receipt and submitted it via support ticket.
It was like 12 hours ago but I didn't get any response yet.
I thought I could get the steam key immediately.
How long is the expected turnaround of a AMD support ticket?
My ticket ID is 351664.
