Swiggy — Order gets accepted and gets cancelled

I placed two orders on swiggy on 28th December having order id #[protected] and on 27th December order id
#[protected]. Both the orders were accepted and both the times the delivery person accepted the order and they made me wait for more than an hour just to cancel it. I had to sleep hungry for 2 consecutive nights. I don't know how they plan to expand with such pathetic services. Also they gave a coupon on 27th December which i applied on 28th order which got wasted. Such poor services.
