IndiGo — Diverting ticket to new flight

Address: Bangalore, Karnataka

I had booked ticket from Bangalore to Bhubaneswar from Bengaluru round trip in May. At that time Bangalore to Ranchi flight was not introduced. Now if I want to convert that ticket to Ranchi it's not possible. This is not fair becuase the other flight was not there and I am booking in the same airlines. Don't you think you should consider to convert the ticket from Bhubaneswar to Ranchi?
