Hey,
Just got an email about PLN being introduced to battle.net.
I got similar email a year ago that said currency change will be not sooner than feb 2024. Now it says not sooner than 30 days from this email.
What makes me wonder is email it was sent from. noreply@ te.battle. net
Is this Blizzard email? It doesnt seems like it however im receiving Blizzard info about games and new features from emails such as @e. blizzard.com
Can a kind customer support confirm if this is fake or not? Thanks.
Yea I rememberd it as well here:
Maybe a CSFR will check it out later today when they have time.
Hey Deed,
This would indeed be a legitimate email. You can find more information, and the different email addresses that we may use in this article. 
What I can do to prevent this change on my account? Because I don’t want to pay 3-4 times more that I’m currently paying in Euro. I still remember when one game shop in S in name change currency and price skyrocket. I know same will happen here. If there is no way to prevent this then I will just cancel my sub.
Typically you can’t. This is generally a country or region wide change to match currency power in that zone. Such as Argentinia, Turkiye etc etc.
