Zomato — refund related issue

Address:

Indore, Madhya Pradesh, 452010

I have ordered food from zomato on 19/10/2018
Order from nafees restaurant.
Placed on 19th oct at 06:41 pm.
Id: [protected]. This particular order was cancelled by the person delivering my order named mr gagan and the company is saying i was not available at the time of delivery and they will not refund my money.
But when i talked with mr gagan he said i rejected your order as restaurant was taking too much time to prepare my order hence i cancelled your order
Please help me to refund my money
