So... I have another post on this issue here:
https://forums.elderscrollsonline.com/en/discussion/comment/6888030. I opened ticket for that and after a couple of days the purchase worked (at least one of them, didn't try to make them all again since my kids left while I waited for a ticket resolution... so... yeah, kind of a bummer there but ok... happens).
So I thought the matter resolved. Now the kids are back home and wanted to purchase some crowns to decorate a house together (as a "reward" for one of my kids). And... same issue again.
As before I tried 2 different credit cards (fun fact is that one of them is the same credit card that was successfully charged for my ESO Plus), 3 PCs, 2 different browsers, same billing address that worked before, nothing worked.
Again I called the bank (one of them... seen no use in calling the other one also) and they said everything looks fine on their end. Tested some other purchases (in steam, gog and some local food delivery) and all went well so I'm pretty sure is not a card issue.
Does this happened to anyone else? Are our accounts flagged somehow (if yes why, we've been playing for years with no issues and pretty sure we've done nothing wrong)? All of us love ESO, and we literally want to give you money for the joy you bring to us (well... usually... now is more like a sour taste).
In any case, I opened a new ticket (200809-007415) but would love to know if this happens to anyone else (is a problem on ESO side), or is just us (bank issue, flagged accounts, country restrictions, etc.), and if it is on our end how to fix it.
Have a great day,
Victor
