Domino's Pizza — refund not get for cancel order for last 8 months

Address:

New Delhi, Delhi

I've placed an order with Dominos on 10th April 2018 at 1am with Rs. 671
They cancelled it after 20 minutes saying that the location is far away and my amount will get refunded within 6-7 working days.
It's almost an year now
And I've been after them to get the refund or replacement order, but they've been fooling me around each time, giving reference numbers but no actual action is taken.They consider customers as a puppet.It seems I've been begging for my own money
Wonderful service by such an esteemed brand !!!
Hatsofffff ... really !!!
Now, They put my call on hold for a long duration and later say that we'll call you back
But never do.
I have attach screenshot for yesterdays talk. They said they will call in 24 hours but not received yet..
Today again i call several times.
One agent told me that contact manager and peovided his number.
Manager is also not responding. I tried several times to reach him.
Kindlt check screenshot for order and other references.
I have to spend much time every week for this non sense thing.
