How do you solve a problem with chronic late-coming of your students?

I invite him to my office or prefer to go to him and talk to him about this matter once with love that he did not respond I will call again and will not try to go to him as the previous time and tell him I will tell his parents to repeat this again and if not respond again I will send a direct letter to his parents to come To my office and then called the student and told them the problem that I tried to solve beforehand did not respond to me and I want them
