Swiggy — order changed as per their desire and late delivery

I placed an order today thru swiggy for 3 pineapple and 3 strawberry pastries order #[protected] from godavri bakers vikaspuri new delhi but i was delivered black forest pastries instead of strawberry pastries and when i contacted swiggy they refused to support and clearly denied the order cant be corrected and instead the accused me that restaurant has sent correct items calling customer a lier when i sent them the picture of the same they start beating around the bush and not ready to support poor troubled customer due to their service failure.
