Pick and pay safety

I was at pick and pay protea glen today and theres a guy who seemed to be an employee from the store due to the uniform he was wearing. he got angry coz i told him not to skip me on the que to go in the back he threatened to kill me and for my safety i took a picture of him and he started to cause a scene until i left the store

Id really like to lay a complaint about him especially coz he’s an employee from there
