Domino's Pizza — order cancellation after the payment through paytm.

Address:

Appa Junction,Suncity, Telangana, 500008

Location: domino's in sun city, appa junction, telangana.
I ordered through the domino's app on 24th february worth rs. 892/-.. Bt the app shows order pending after the confirmation of paytm payment. Later i called to confirm what's the issue, i was told order is cancelled and refund will be initiated. I called the domino's several times, they said it will be done soon, i waited for more than week.. Still refund isn't recieved. I called today again and they said it's done and the problem is with paytm service. So, i checked in at paytm helpline.. They said domino's hasn't initiated any refund. I called the domino's helpline again regarding all these, they asked to file a complaint at this page with a picture of my paytm transactions to see if the amount is credited to me or not. This isn't about a small amount, so i am here with my issue. I hope it will be resolved soon.
