I purchased the The Elder Scrolls® Online Collection for $79.99 which I thought was the premium package. I do not believe I received the rewards. Is there a higher package?
1. Which rewards are you referring to? Are you talking about the chapters, the DLCs, preorder/collector edition rewards?
2. Where and how did you purchase the game? Steam, Xbox, Playstation, digital, physical, new, used?
Depending on the answer to these questions the answer to your question will change.
