Swiggy — Delayed in order and delivered after also 1.5 hours

I ordered Biryani on Swiggy from the restaurant which is about 6km far from our home. The restaurant has prepared my order on time but the company's delivery agent was not moving away with my order and was waiting for the another order to complete after my order.
After 30 minutes of waiting at restaurant for the another order he started moving from the restaurant.
Then he delivered another order before my order and after that he delivered my order almost after 1.5 hours. The food I got was completely
cold because of this much delay in delivery.
Although I paid for my delivery I was not getting my order on time. The company has to prioritise the orders tp get delivered.
