Swiggy — Stale and inedible cake

Iordered a butterscotch flavoured cake from Cafe Coffee Day via Swiggy.The cream on the cake was stiff and stale, even the cake tasted like medicine and nailpoilish .After one bite i did not continue to consume the cake and contacted swiggy with my complaint.I had chat converstion with 5 representatives and 1 phone call .They said it was a packed food and nothing could be done, I asked for a manufacturing date and expiry if it was a packed food but they denied providing me the same .
In my knowledge all packed food are labelled with manufacturing and expiry dates .
I also tried contancting Cafe Coffee Day but got no response for the same .
No compensation in cash or kind was offered by Swiggy..
i want to get refunded or compensated in kind via some coupon worth my spent money
