Account locked unnecessarily

So I launched battle.net this morning and was greeted to a lock icon next to my play button. So just asking why this is and how can i resolve it.
The icon says “This account has been locked.”

PS. it’s next to my Call of Duty Modern Warfare icon.

Open ticket to Support team. They can help you. Good luck!

@IonutCatalin: Not in this particular case, unfortunately.

OP has posted about this several times already… got a Blizzard response here:

He/She needs to contact Activision.
