Swiggy — Received Incomplete expired items

Address:

Kolkata

Hello,
Received 8 250ml Bottles which were already expired condition, instead of actually ordered 1 Litre 3 Bottles.
Many times open Swiggy Chat, Ms.Ridhi was providing the refund but all of a sudden senior executive refused to refund and ask me to drop an email. From email there is also no satisfsctory response. Now I need complaint to FSSAI that company serving expired items.
