Air Asia — not letting board without reason

Sir/madam i m a student in singapore, l booked you flight from atq to kul and from there i booked scoot tr453 to singapore but your staff at atq airport didn't let me board after checking and they behaved very rudely, said i can board as this flight will land on different terminal than the terminal from which your scoot will depart, that is t2 of kul so we can't let you board from here, i showed them my visa, my student pass my scoot ticket and requested them that i had my class on 24/6/2019 and i can't miss as i will be fined and need to produce reason certificate for not coming to class, and also i m from middle class family can't afford loss of my two flights that costed me around 40, 000. But they said no you can't, u can only go in airasia from kul airport and that is on 24/6/2019, that itself means waiting there for 20+ hours on kul airport just for same airlines plane, means i can't go on any other plane from therebut yours. But why, what is your policy. I earlier came by your airlines but you this time made me cry in real sense and broke my trust, i pleaded there but no avail there answers changes every time with no logic, once they said from terminal t2 kul you need pass/ malaysia visa to fly scoot to singapore otherwise you can't as t2 and the terminal on which the airasia d7 189 will land are very far apart and you need transit visa for that but when you book airasia then no matter which terminal you are but can fly to singapore, but with other airlines we can't allow you to fly to singapore so hence u can't fly from amritsar. Sir what is logic please explain me. I need clarification and action on respected athuority, and my full compensation of both flights as i was not at mistake, how can i be at mistake, when it comes the talk of other airlines they said u can't, if i book your airline from kul (Malasia) mistake vanishes. U said to me you have to obey us, but are you obeying yourself really, please help me as this in turn will help you. It was, rather it is, such a headache, mental agony i m going through, can't sleep this night becoz of you staffs negligence. U made my nights here restlessas u are wholly responsible for my loss. Plz pay attention. And resolve issue asap. My mobile no. [protected]
