Swiggy - Swiggy cancelled my order and charged 100 order amount as cancellation

I palced an order on Swiggy for two *kg cakes from Bakingo, Shahpur Jat. The order amount was about Rs ****. Immediately after placing the order, i called up Bakingo to confirm the order who said it would arrive within a hour. After about an hour and a half, i clled Bakingo again who told me the order has been cancelled! The delivery boy stopped answering mine and baker's calls and finally said he took the cakes home. He even tried to blame the guards at my residence (who are extremely responsible folks at IIT Delhi) but the guards took his name and details in the entry records. Swiggy decided to charge me the entire amount as cancellation fees. After a lot of haggling with their inept customer agents, they decide to refund me Rs ****. I would like my full refund and an apology for destroying my daughter's third brthday party.
