Swiggy — delivery in 7 minutes, it showed estimated time of 30 minutes

The estimated time of delivery showed 30 minutes and the order was delivered in 7 minutes so there was no one to take the order. The company cancelled the order and charged me cancellation fee. What sort of fraud is this. I was home in exactly 2 (Minutes from placing yeh order. But in mean time the delivery was cancelled by the team. I asked to speak with the call center superior and give a justification as to how and what is the time management. If you are delivering in 7 minutes against estimated time of 30. What sort of time management is that. I need my amount to be refebuded to me and not be charged in next order.
