Swiggy — Frustrating customer service

Website:

Swiggy

I have ordered special chiken Biriyani with two pieces of chiken from swiggy but I got little rice with one bone and potato, I took pics and complained about it at once but they told can't do anything only can refund 48 /-. I totally disagree with this.But they say IT IS BESTCYHEY CAN DO.
Before also same thing happened for wrong items or spoiled food, I have even mail to support team but, nothing help.
I feel this is kind of frustrating customer service from Swiggy
