Swiggy — disgusting customer service!!!

I ordered a burger on june 21 in the evening and i was called and informed that the order cannot be delivered so they would provide me with a refund. After the call was done i could see my order was marked to be delivered and i didn't receive the refund. I contacted customer service and requested the refund, they informed that the refund has been processed and that it will reflect on my account. I have been very busy but placed 2 orders with swiggy after that over the weekend but didn't see th refund. I am on a chat with your customer service representative now whose name is pranav. He is full of attitude and is the worst customer service agent i have ever encountered. He refuses to help me directly and also calls me a lier even after i provided him the screenshot of the previous chats. He doesn't care if i make a complaint or escalate this matter, he remains on his own ego and makes me feel pathetic. I am still waiting for a refund and would also like to know what is swiggy doing to compensate such inconveniences!!!
