I had just got the notification that I had gotten my arena chest for the week and was happy with what I was to receive... then the items never came.  After clicking to accept the items and close the popup like I had done before, no items in my inventory or inbox or at the portal.  I'll be quitting and ruling this as a scam if the items do not show within the next 16 hours.  Soon to be known as Raid scammer legends.  I'll be on a campaign to discredit anyone that supports you and have already left a scathing review.  Your rating has been slipping I see, good.
