In general I'm disfavorable towards treating the spirits so harshly. If one doesn't want to work with the magician, I favor ending the contract on as good terms as possible rather than castigating the spirit.
You should also consider that lottery magic is particularly difficult. She might be able to fulfill the rest of your contract, but the spirits aren't omnipotent. They can't usually stretch causality as far as winning something as rare as a major lottery payout. If you do the contact you've written here, I would remove that aspect from the initial contract. Then, if you have time and Astaroth isn't too antsy to leave (appearing to us is said to be uncomfortable for the spirits), you could make a separate contract where if you win the lottery she gets valuable offerings. If not just call her back up later with your existing pact and do the same thing. This way if she fulfills the rest of your desires and is otherwise a good business partner, you don't feel compelled to castigate her for doing her best and failing.
