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.
