I have booked tickets from pune to bangalore to and from on 20 and 25march. But ticket gets cancelled by jet airways. First when i called costumer care, they replied and asked me to check for convenient time to reschedule. So after checking convenient time, i am trying to call customer care from last 3 days onwards, but no one is receiving my call to provide proper solution. Please help me as this journey is very urgent.
