Hello all, alt account or new main idk. I restored my computer and lost my blizzard account with call of duty. Tried every email I have ever had but always says no account made with those emails. I have proof of purchase through paypal, with my lost account but cant login. i do have the battletag still linked to my activision account. please help me 
i have the same issue, i lost my alt acct, with BFA (WoW), but i know the battle tag
same thing happened to me, mine was hacked and i cant get into it, and with blizzard level support its probably gonna stay that way
