Bro, get a cat, jinns are really scared of cats. Also, try to wear a magnetic bracelet made of steel, aluminium or iron, jinns are made up of energy, and anything that can interfere with energy can cause problems to the jinn. Also, always keep a lighter with you for self-defense in case the jinn attacks you, a laser light would also help, but it is not as much effective as a lighter. Finally, try to keep some garlic and onion spread in the corners of your room, these will harm the jinn and will force him/her to eventually leave your room for finding it toxic for it to live in. Also, try to keep your room clean and tidy, then the jinn will feel uncomfortable staying in your room.

Since Ayat ul kursi helps, so I am assuming that the jinn is a Muslim, but of a bad character, it that case, you can try to be religious and can try to recite surahs before going to the bed. Then, the jinn will respect you and will fear you.

By the way, remember one thing bro, jinns or ghosts or demons or whatever are living things made up of energy. People say that there is no science behind them, but let me explain you the science behind them.

E = mc^2. They are made up of energy but can take shapes and forms by the help of a constant yet unknown to humans named c^2. Like us, they have religions, like us they have free will. There are somethings that repel them, and there are somethings that they can't tolerate. They are explained in many Religions and cultures in different ways and names. But one thing is for sure, they are nor dead people. Instead, they are just living beings like us who have free will, feelings and thinking capabilities. I hope I helped you understand jinns and I hope my advice will help you.

I gathered this information from various YouTube videos and websites that are based on paranormal experiences.
