I hope for you this will make them think about their reputation and the bad publicity they might get if they don't refund you in accordance with their own terms and conditions.
they don't care about their reputation. ChangeNOW has always been selectively scamming, just like Freewallet and some other instant exchanges.
Wallets not using DEX for their swapping feature should be considered dangerous now.
they always have been dangerous. atomic wallet, exodus, etc... all those wallets use third party instant swap platforms, and they pick the scummiest ones because they pay the most in affiliates fees.
