Sorry to hear this. I take it there are security cameras in this store? If so, you can sue the living fuck out of 'em. Find out about the camera footage and find yourself a good lawyer.
If you're a female and you wanna hit ppl, you deserve what you get. Don't dish it out if you can't handle the consequences. The last little bitch that swung on me, was shitting teeth for a week. I made sure of it.
