UberEats BAD SERVICE DELIVERY

I ordered hot wings from Chicken Licken through UberEats. Some of the wings were not fully cooked. I called the store and they were willing to refund me, but since I paid UberEats, the store manager wrote to UberEats to refund me, I also wrote to them within an hour after receiving my meal. UberEats confirmed immediately that they will refund me. After a week, no refund came through, I emailed to UberEats, they did not respond. I kept on checking with the store, but the manager who assisted me initially was not on duty. After a month the store manager wrote to UberEats, they responded that they want to deal directly with me as the customer. I sent UberEats an email, they said they did not get my complaint. I forwarded my correspondence with them that I wrote within an hour after receiving my complaints. UberEats sent me an email that they cannot refund me since 48 hours passed. They failed to refund me within 48hours, but since it is their fault for not refunding me, they said their policy does not allow them to pay after 48hours. I have the evidence that I lodged a compliant within 12 hours, they did not refund me then. Now they are refusing to pay me because 48hours passed. They don't have a good customer service, their delivery takes long and they don't care about customers.
