Ordered food online with zomato on 8-october-2019. While the delivery assistant was about to deliver me the food i ordered, he called me and said, his vehicle was broken down hence he asked me to cancel the order promising me i will get full refund. Hence i cancelled the order. I reached out to zomato customer care and they said they can't refund the money. I raised a complaint in twitter, then i got acall from zomato, said they will credit the refund to my paytm account in 24 hours. Still i haven't received the amount in my paytm. They never responded after that. My paytm number: [protected]
