I think your chances of getting your funds back are very small or I could say impossible, it's not that Roobet has no intention of returning your funds but the security system they have to maintain and this is a lesson for anyone to be very careful when sending funds, even if that happens. in exchange they will do the same, maybe you can try again to apply for a refund but if they keep saying no then you won't get it
I wrote to them several times, but they just copy-paste the same text - When the BEP-20 network is touched, they cannot help because the entire system is automated.
That's why I'm writing here because maybe someone from here works at RooBet from the technical side and can help..
