KFC India — One burger not delivered but billed

Ordered from KFC City Center 2 Kolkata block C city today at 19.19 hours . Billed amount 683 for 1 popcorn (large), 1 chicken zinger combo and 1 burger (178 inr) as take away but delivery person didn't give 1 burger which I found while reaching home. Need refund of this amount of 1 burger that was not delivered but billed for 178 at the earliest. Also, would appreciate if such staff are getting punished to avoid such issue in future
