Zomato — no refund for long time against non-delivery of food

Food was ordered through 'zomato' from our home by my daughter using app in her mobile phone, and payment was done using my credit card on dec 07, 2019. But, the food was not delivered, and when complained through chat, refund was promised. But, even today, no refund is received.
