casino switched my pending withdrawal to a different payment method without asking

So here’s a weird one, I finally ran good and cashed out a decent chunk from a crypto casino, chose the usual crypto payout, and checked back a day later just to see my withdrawal got switched over to a random e-wallet I haven’t touched in forever. No warning, no email, not even a “hey are you sure?” My account and details were the same as always, but poof, new payment method.

Anybody else ever had this happen? I keep a little list of casinos I won’t touch again, and this is feeling like another entry. They keep telling me it’s “standard procedure for large wins” but I don’t see how changing payment types behind my back helps anyone except their bookkeeping.
