I hope this expresses your meaning:
I need to inform you that I am having a problem with him (who?). My employer is from another company in Mysore. I live in a rented room. One day I was waiting near the dining hall to get my room key from my friends. The watchman, Raju, told me I must wait outside because I am not allowed near the dining hall. I explained to him that I was just waiting for my friends to bring my room key. Raja argued with me using bad language. He always acts badly toward me and the other boys. I tell the warden that Raja is against me, but the warden does not respond to my complaint. I am worried because no one is helping me with this problem.
