Afm Events — need refund for 6 tickets for diljit concert

We booked 6tickets for diljit dosanjh show at pune for 20th october. Just before 1-2 hours we came to know the show has been cancelled due to some reasons. We have been chasing the team for past 3-4weeks but no one even bothers to pick up the call or respond to my emails.
I have been calling them regularly and chasing over emails. This is highly unprofessional behaviour. I need the refund of my ticket amount as it was a no show event. Attached the pic of tickets
