Domino's Pizza — urgent- refund of money

Address:

Amsri Plaza, Near Baseera hotel, SD Road, Secunderabad, Telangana, Hyderabad, Telangana, 500036

I have ordered Pizza at Dine in at Secunderabad Domino's Pizza dated on 30th September of One veg and One Non veg and one Taco. They have made the Bill of amount Rs. 744/-. Which actually should be of some offer and discount has been not applied . As I questioned them, the staff working there told to make another new order. And told that the Total amount of Rs. 744/- gets refunded within 10 working days. And after contacting the Branch manager of Domino's located at Secunderabad for several times, he told money gets Refunded. There is no use. And it has been One month as of Today (30th October) and I didn't receive any Refund yet. This's so negligible by the Staff working in Dominos. I tried calling customer care number of times, I have suffered a lot as Am continuously asking them for the Refund status. I need the money to be Refunded and this is not at all acceptable.
