First Flight Couriers — Complaint about courier J991M5878744

Address:

Bareilly, Uttar Pradesh, 243001

Worst courier service. Packet delivered were opened and half of the snacks were missing.
Courier boy fought for delivery at provided address & asked us to pick at Bus stop. After several phone calls, when delivered he commented "Ïtne paiso mei ghr tk nhi deliver krte", if we define the rates of workers? why we should suffer if salary is less by company? When we opened the cover packet from courier, our original packet was in worst condition (attach pic). It was already opened and snacks were missing and messed up together with extra waste. It seems packet was opened and snacks fall down and somebody refilled it with dust from the floor? We were not informed that sealed packet will be reopen somewhere in the route for extra check when packed? and if we are missing with original material where should we go to?
