<human>: Summarize the given text in a few sentences.

I work at a local gas station in Southern California, and it all started when a customer started getting hostile, and threated to wait outside the gas station to beat me up. I proceeded to ban him accordingly from the store, filed a store report, and told my manager about this guy. (apparently one of my coworkers talked to him before the incident and he said he was on probation). The guy who threatened me keeps showing up at the store, even when i told him countless of times that he is banned, and today it makes the third time he threated me, called me a "motherfucker" , and was extremely hostile i proceeded to call the police, and to file a police report (like my manager, and the owner told me to do so) and the police man refused to file a police report, and he also refused to shake my hand and introduce himself properly (not like it matters but i think he was a bit racist). I've never been hostile towards the man who threatened me, and ive always tried to tell him to leave calmly. we have video, and audio proof from the store of him threatening me. he has threatened me three times. He knows where i live, and i have younger siblings who i worry about. thank you for your help.
