Swiggy — Order id[protected]/Need my refund back

I ordered 3 items from swiggy with order id as[protected] on 24 May 2022 and one of the item was missing choclate mousse even restraunt accepted that they missed to send the order and told me that swiggy didnt even contacted with them. Swiggy is telling they investigated and they can just forward my feedback and cant compensate. But I need my amount back.
