When do you plan to answer? I've been waiting for more two days. I thought the amd support service was better than that.
You are confused. This isn't AMD Support. This is AMD Forum where Users help other Users with their computer problems or issues. It is run and managed by AMD Employees but their job is to moderate the Forums and at times help solve certain issues that may arise.
One of the Moderators here could probably help but that is up to them and if they have the time.
This current thread here at AMD Forums may give you some indications of how long it takes to get your games (2-4 days): AMD Rewards Coupon verification
Have you tried actually contacting AMD Support from the link at AMD REWARDS website from here: AMD Rewards
