E-Z Mart complaint: Defamation of character by employee that got me banned from the only store open at night

I went in to ez mart to get gas and the employee was rude and spoke to me with total disrespect. I told her I’m a customer and she should be more professional . She stated her daughter broke her leg and her boss told her she doesn’t have to serve me if she didn’t want to which seems from a personal issue the employee has with me over me taking care of her grandmother she has nothing to do with.

The employee claimed I told her I wished her daughter dead which was a complete lie and I even told the manager that said she watched video and I have been tantalizing her employee. I told her she needed to w a tch video cause if she had she would of not lied as well.

I’m banned from the store and it’s the only store open after 8 or 9 pm. I am going to sue the employee for fefamatuon of character for it has caused me hardship from getting anything we need like gas,food, drinks etc. I will call corporate and am filing a lawsuit Monday morning
