Bikanervala / Bikano — less weight along with an human hair in sweet box

Purchased a mixed sweet box pack no.2623 @Rs.2586 on 3/11/2018 from sector 29 gurugram outlet. On checking the weight of the pista louj / kaju roll etc, found the actual weight 140 gm each instead of 160 gm along with an unwanted long human hair .
Weight re-checked by their own staff in their outlet in sector 29 gurugram. Then they tried to add sweets to increase weight and also offered me the same free of cost.
This is highly objectionable & deplorable keeping in view reputation of Bikanerwala. An early reply is solicited.
