Well, I actually read the email from the image OP shared and while it may seem to have a misleading captain, I think it's not completely so misleading because they are asking you to claim the lottery ticket which can grant you the opportunity to luckily win an amazing prize, believing that after you win that prize, you will have to withdraw your prize. That's probably why they label the email as "withdrawal notification" But it's kinda awkward tho. Just my opinion.
Personally if I received an email entitled "Withdrawal Notification", knowing that I had no current withdrawal, then I read that the contents of the email that it was a mere offer to join a lottery for free, I would merely dismiss it and forget about it.
OP is probably overreacting.
I use BC. Game casino too but didn't receive this email, the last email I got from them was sent on the third of this month and it was titled, "⚽️ Euro Cup 2024 at BC.GAME: 3 Epic Events, $100K+ in Prizes! 🏆
But the contents of the email is a withdrawal notification?
