Has anyone experienced ACCOUNT LOCKED IN BATTLE.NET?

[BoiGwapito]

So I purchased the VAULT EDITION for COD MW3, when I was playing with WARZONE I got suddenly disconnected and there is an ACCOUNT LOCKED IN BATTLE.NET, so what I did was I linked my STEAM to my battle.net and downloaded WARZONE. Law and behold I can launch COD MW3 with no ACCOUNT LOCKED.

So my question is, how can I even violate BATTLE.NET TOS I wasn't even able to play COD MW3. I just purchased it a few hours back.

I have no BAN ON MY ACTIVISION ACCOUNT

Refresher, purchased COD MW3 a few hours back, was playing WZ and suddenly got disconnected and suddenly my account was LOCKED. I checked https://support.activision.com/ban-appeal no BANS in any COD GAMES. Tried multiple times in getting in touch with CS through CS TICKET and what did they reply? THE GENERIC REPLY they ALWAYS GIVE. I spent $105 on the VAULT ED and this is what I get?

So I'm beginning to regret staying in BATTLE.NET I should have migrated to STEAM.
