Domino's Pizza — Refund Not Received after 20 Days

Address:	110024

I had Ordered Pizza from Domino's on date 10 Nov 2016 From Vasundhara Enclave Branch, I Paid in advance 289 for order through my Debit card, however, I had not received any order in next one hour whereas it was mentioned that it will be free if not delivered in 30 min. nobody even tried to call and update me I kept on trying to connect for the status of my order but no one responded to my calls, even though they had not provided delivery boy's contact no. so finally after waiting for one hour and 100s of failed call attempt they responded to one call and that too they started playing call passing game with me at least 4 people talked me for cancellation. at last, I successfully managed to cancel my order, A guy told me that your refund will be done within 5 working days and I was ok with that, after 5 days I tracked my refund status, I got nothing in my account so again I contacted to customer service than they mentioned that your refund will be done in 7 working days so wait 2 more days, and when I again approached Dominos after 10 days on social media they said we are checking with concern branch and will contact with in 24-48 hrs, an SPOC called me next day and asked detail and I shared the same but till date I have not received any refund from Dominos, recently I got a message from Dominos that we are trying to contact you but not able to reach you, I don't understand when I am available 24*7 on my shared contact no then how they are not able to reach me, even I have miss call alert service on my no, there also I have not received any update that they tried calling me, they could have reached me through mail if further information required but they did not try that. Now I am totally pissed off with the situation, I am mentally harassed with Dominos refund policy and their service, it has been almost 20 days following for just a small amount.
Now I want a lesson to teach them for harassment.Please help me out to resolve this issue.
