Still no update for me...im on day 7 without being able to access my guildbank, my guildstores or any form of zoneinteractions or whispers...a whole bloody week. Still no explenation or info what has happened. Tempted to quit the game tbh.
I´m paying for eso+ sub since launch and I find this unacceptable. Waiting on agent....yeah right..

it's been a week for me as well, no warning, no explanation, just silence

edit: I was eventually helped. I had used an add-on, GodSend, since I'm guild leader and needed to message my guild. I didn't use it often. It had been over a week since the last time. The tech support person that helped me suggested I adjust the time between messages going out. I had used this a few times before with no problem. It had been suggested by a fellow player, that with server lag, the messages piled up and sent all at once triggering a social ban automatically. I'm very grateful for being helped, just not sure why it took a week and having to communicate outside of the tech support ticket. Also not sure why I wasn't given any communication, such as an auto-email, to let me know that a social ban even occurred and why.

Day 9 for me....still waiting on 007....patience is a virtue...i guess

@Valerie_Sinclair I have recieved 3 notifications from @ZOS_BillE , each one asking me to return within 48 hours if no resolution to my ticket/problem. The most frustrating aspect is that have no clue as to what triggered the ban. I´m suspecting
it must have something to do with a few trademessages regarding motifs in zonechat, 5-6 all-in-all, but that seems strange.
Anyway im keeping my fingers crossed for this issue to be solved soon. Thx for your concern. Have a good one!

So it is been 17 days since i got muted, and still no response, and as promised, i've cancel my sub

12 days later the issue has been resolved. As i suspected it was some trademessages in zonechat that triggered the ban.
Really silly imo, will have to be careful with trades etc. from now on.
