fanduel casino credits expired overnight even tho app said 3 days left

Logged in to use some leftover credits for blackjack, the promo page clearly said they expired in 3 days, but woke up this morning and they're just gone. Support says “terms and conditions,” but I double checked and nowhere does it say they can just zap them early. Feeling a bit tilted since I plan my sessions around these little bonuses, especially for trying out different live dealer tables without risking my own cash.

Has anyone had this happen before or is it just my luck? Do they ever fix it if you reach out again, or am I just chalking it up as a loss and moving on?
