Doesn't studies and is problem for us.

He never studies and if we shout at him or anyhow let him make study he never does, he has an laptop for online classes but he has barely ever attended any class on it, he has an very high addiction of watching an turkish webseries, he has watched each episode of it nearly 4-5 times, he even watches gameplay of various youtubers, and if we however not let him watch or let him sit idle, he makes irritating noises and just constantly repeats movie dialogues and laugh,Yesterday his dad beated him alot due to this so he ran out of the house and went to our shop and said that i will sleep here and will not go to home, his parents are scared that he will run away from home bcoz he is seriously becoming an disaster for them, he is sitting on laptop for straight 8-9 hrs, his situation is becoming worse day by day and bcoz of him we are not able to study at home, please suggest me what should i do ?
