Zomato — money deducted but not received food

Hi that the same happened to me...I ordered dominoz pizza by Zomato paid online and after 30 min I got call from dominoz they told me they can not deliver to my address like happen same with you and when I asked for money back they told me you have not paid to us by the way your order is cash on delivery this is what dominoz mentioned to me and when I initiated the chat with Zomato they told me I have not made any payment to them they entirely lied even though I was having my online prove of transaction due to my tight schedule I ignored this. Because Zomato did not helped me ..so after 3 days I approached to my neighborhood frnd..he is working in Zomato I shared my concern and my number ...later on he called me and told me yup I checked for your order you paid but did not recieved pizza...then he placed a refund from his side I got my money back ..but here the point is why Zomato denied it for dominoz for giving support ...why do dominoz denied me and told me it was cash on delivery and later on over the chat zomoato it self denied that I made an payment to them. ..why ? Why ? ...all this makes me frustrated and I considered my self as an fool by using Zomato ...my registered no is [protected]
