Assaulted by a male employee at South Beach Durban

I am a lady and was assaulted in December by a male employee in this garage. They held me hostage inside the garage and took a cool drink I paid for and this matter has not been resolved up till now. I have not been repaid either for the cool drink I paid for which was taken from me by the hooligan who works at this petrol station. He followed me even after leaving the petrol station to further threaten me.
