You could try emailing the breeder, but I'm not sure if any guarantee temperament... But you've only had her 3 days, I would give her some time to settle in. What's her set-up like? Temps? Hides? Your snake isn't violent, she's just defensive. I have one that sounds like your bee. She's gotten better with time and a super cluttered enclosure, but I don't think she'll ever be as sweet as my male. I would try to work with her, but if it's something you don't think you can handle in the long run, I'd consider rehoming her.
