Based on the time of this transaction, it's quite close when Betfury were attacked by hacker on March 21,2020 so there's a chance your account has been hacked too. Do you activate 2FA on your account?
As you said it's a small amount money, how come a scammer interested on small not a big one? Betfury wouldn't ruin their good reputation.
Better to provide any proof as anyone suggested above.
they have no reputation, reputation is not an argument, but a screen to hide their crimes, they steal small money, big players can tell about it all over the Internet because of big money, I am a small player and I cannot spread this information .
Even you do not believe me just because the amount is small and they know that you will not believe me, if a million were stolen from me, you would look at this situation differently
