Can I get justice from someone who wronged me?

I am a woman who was cheated by a Muslim shopkeeper in his fifties. He took what was rightfully mine, and when I asked for my rights, he became aggressive and came at me. I never disrespected him. Yet he pretends to be a pious Muslim in front of others. When I said, 'Allah is above us, give me what you owe me,' he replied, 'Don't talk to me about Allah.' He even deleted the camera footage. He laughs in my face and mocks me. I have no male family member to stand up for me. He caused me serious financial trouble, and I cursed him and prayed against him many times while crying. Even my friend felt sorry for me. I know I am a vindictive person, and I know I shouldn't be, but I am. When someone hurts me, I remember it even 40 years later. My friend says that if I sincerely cursed him from the bottom of my heart, what he did to me will come back to him many times over. He caused me €1,000 in financial loss. Will he suffer something many times worse than that because of what he did to me?
