The ESO payment system appears to be struggling with processing Twitch Purchases. I have experienced unprecedented delays of receiving my crowns; and often receiving the wrong item (e.g. bought 5500 crowns and received duplicate copies of Summerset ). Normally, I would just shrug this off and accept the delays but the support representatives are beyond frustrating. I have undergone weeks of back and forth Copy/Paste responses in which they do not actually review the ticket and attachments.
I am not sure what is going on behind the scenes, but this is an ESO issue; as I dont experience this elsewhere. I am going to request that Amazon investigate this issue and suspend their Twitch purchases if this is not an isolated issue.
