[Resolved]  Swiggy — Missing item not delivered and neither did I get any refund

I had ordered grocery from swiggy and order was eligible for free "Aloo Bhujia" worth rs 91 but it didn't got delivered with order. When i contacted swiggy support with this issue, they only wanted give me a coupon of 50rs, which is absolutely of no use as swiggy app has 100-120 rs random coupons available at any point of time. So i asked for only 50rs refund to the source of deduction which they denied.
