Zomato — money debited twice

Address:

Mumbai City, Maharashtra

I had placed an order via zomata on the subway restaurant, cbd-belapur, navi mumbai and had accidentally clicked on the cash on delivery option. I called them up and told them that i will place the order again but this time paying with my card. They agreed and told me that they arent gonna make the order and that cancelling the order will take an hour. I agreed and placed the order again and paid by my card this time and he confirmed with me that the transaction through the card has been made. Upon arrival, the delivery man charged cod payment and i had to pay because he said the amount was unpaid whereas the subway owner says ive already paid via cash.in this sort of confusion, i ended up paying twice and now i request a refund for my money as the order i payed for via card has never been delivered and i have been charged twice for one order.
Pls look into the matter
Regards
