I have made an order from the zomato app at 11:18. I want my order on time so i paid extra 10rs against their "30 mins or free" offer - order id-[protected]. Then i received the order 6 mins late.in addition to that, i received a cold burger - as cold as icecream so first i complain about 30 mins or free policy and they refused to refund, so then i complain about cold food and asked them to change it with the hot one. They denied. I am giving a complaint because it been several times where they mostly don't give a solution and only says we will serve you better next time.
And now its a kind of harassment and over the limit
