After a player purchases the Clockwork City DLC, the Crown Store should
not offer the Clockwork City Collector's Edition. Also, perchance the player buys the Clockwork City Collector's Edition, then the Crown Store should
not continue to offer the Clockwork City DLC.
There is nothing gained that is worth the cost to buy both. For whatever reason, I overlooked that I had already purchased the Clockwork City DLC, and bought the Clockwork City Collector's Edition because it was the only one that was available. At the time, I assumed that the initial release of the Clockwork City DLC was no longer available, because I did not recognize its darkened panel among all of the other DLCs which I have bought previously with Crowns.
Afterward, I realized what had happened, namely, an expenditure of 4000 Crowns for 5 Crown Experience Scrolls which I don't need, a Mount that I will never use, and a Pet that I will not include in playing the game (nor will I display either the mount or the pet at a homestead).
So I want a refund at least of the Crowns that I spent first for the Clockwork City DLC. ZOS can have the other items back if they will refund the 4000 Crowns for the Collector's Edition instead. However, I cannot find a way to contact anyone at ZOS about this matter.
The Log-in for the Support feature of the ZOS website
fails, without any explanation, although I correctly enter the user ID and password for the "Account" and for logging-in to play the game. As far as I know, the user ID and password to log-in to "Support" are the same as for the "Account". (The user ID and password are different for the ESO Forum, however.) In fact, when I use the "Sign Up" feature on the page displayed by
https://help.elderscrollsonline.com/app/utils/login the result is a display of the log-in dialog for the "Account".
Evidently the ZOS website Support feature recognizes that I already have an "Account" at least while I am, in fact, logged-in to play the game. But there is no access to anyone who can do anything about the Account and/or transactions at the Crown Store. This situation is no way for anyone who is serious about providing ESO as a service to
run their business, because it will eventually
ruin their business.
