Bargain book is promoting violance

On the 2th of march 2018 around 14 .30 i went at bargain book store i was, trying to purchase books.and when was about to pay i asked the cashier to help me fast because im running late .and she told its non of her business that im late and that im not gonna come and tell them what to do.i rep**** by saying i dont have time for this .and i don't expect this from you at your age and at work this is foolisheness and unprofessional .and she start shouting and saying hard words that i am a fool ,i sleep with all mean for money ,i do ********s and i dont have kids at my age .i will never go anywhere in life .i rep**** to her saying i dont have kids who don't know there fathers and i was shouting telling her to change her ways ,the behavior wont take her anywhere.and she took something like a box made of metal and she threw it at me and a book it hurt my thumb .she literally come want to hit me on my face i pushed her back so i can protect my self .customer that were in the store told me to leave her .and one of her colleague stopped her .i contacted there area manager he told me they will go through the footage and get back to me .HR from bargain books called me threatening me telling me ive got personal issues ,i can go to police station and do what ever i want they are a big company. I got emails from them threatening me not take this to the media ,and protection order to never enter there store since im harrassing there staff.and they don't wanna discuss this matter again. After i was harrassed by there cashier they say she did nothing wrong they actually promoting violence .im so disappointed by bargain books really .
