Angry with my colleague

Really cannot stand this colleague of mine. He is the most senior associate engineer and the most slag one around. He is also full of excuses and didn’t want to pick up phone call even he is sitting at his desk. Other colleague also ask me whether is he around and want me to ask him to pick up the phone!

Now there’s an issue regarding work. Supposedly under his area but he use this and that excuse and want to push away responsibilities. Say he don’t know what’s going on. I want to reason with him but he don’t let me speak! For god’s sake lor. I don’t care lor. I’m not going to take up his job. Why don’t he give me his pay? Bloody angry.
