Pizza Hut India — Waiting for the refund

Address:

Chennai, Tamil Nadu, 600091

On Dec 24th 2016 I placed the order and cancelled the order on the same day because they didn't deliver it on time. I request around 7.30 pm but till 9 pm they didn't deliver because of the communication gap between the customer service people so based on that i cancelled the order. They said they will refund the money within 10-15 days but it almost 30 days nothing was done. I spoke to customer service person twice regarding my refund. They inturn and advise me that they will ask for call back with an update. But i didn't receive any call back from them when i called them twice. I thought they can't deliver the pizza on time but still they are following the same rule while refunding my money. I want my money need to be refunded immediately. I never seen any worst service before.
