I have made a tickt with two passenges my mother and my brother from paytm. Bt due to some prblm my mother was not able to come so i csncelled her tickt. I got mail messages nd new generated ticket on the name of my brother. Bt at the airport airline deinied nd said his ticket is csncelled instead of my mother. Nd no one took response nd he has to left his flight nd made another tivkt of 15000. No one is taking respinse tiwards this. Even they got another tickt of his name bt said hos tickt is cancelled not my mother. Paytm is saying its airlines falult nd airlines is saying its paytm fault
