Hello mate! I think it is better to create a ticket to Blizzard directly, so a dev can answer you about the specific problem you are having! Here you have the support URL: https://eu.battle.net/support/en/help
I hope your issue solves soon! Have a nice day!
remove your email address, its half of your account details.
Likely your on wrong region tho
Hey there Zzo,
I have edited your ticket in order to remove your e-mail address. Please do not post those details in a public forum.
With regards to your issue, as Winchester above mentioned, this most likely is either you have logged in the wrong region, or in the wrong Battle.net account.
Have a look into this article for more help.
