Zomato — not refunding the amount

Address:	500032

I have ordered the food in zomato and paid the extra charges for extra quantity, but they provided me worst service. The food quantity is not even equivalent to the normal charge but i paid extra amount for extra food also. And also the food got cool down completely then whats the use of delivery charges..
They did chat with me for continuous more than 2 hours..
I facing issues like this repeatedly but zomato is simply looting the money and trying to manipulate with offer codes.
Even in the chat messages they are answering same nonsense repeatedly.
If i am asking for complaint mail id's and twitter social accounts they are not providing.
They are simply telling that they will serve best in future, why should i pay now if they are serving better in future i will also pay better amount in future.
Please solve this asap and refund my full amount.
