I have ordered pizza on 8th november 2018 and paid through internet banking. It was an advance order and before confirming the order i have to cancel the order. After 12 days i contacted the customer care asking about the refund. They told that they will contact me within 24 hours and gave me a reference number (#7394891). But no one contacted. After two days i called them again. This time they told that they will contact me within five minutes and didn't contacted. These people are wasting time and money of customers
