Madhur Courier — parcel undelivered

Address:

Bhopal, Madhya Pradesh, 462021

I sent a parcel on 28th Feb by madhur courier services bhopal to BITS Pilani Goa(consignment number: [protected])...the courier company promised that It would reach by 4th march...I have been trying to get details of its whereabouts since then...I would call them 20-25 times daily...to no proper response...its 19th March and it has not been delivered till now...I told them I would file a complaint for their unprofessional manners...to which their response was you may do so...they are so sure that nothing would happen to them...no matter how they behave...I tried calling customer care services...again they don't work either...I never knew a small parcel could cause me such great levels of mental agony...I feel so harrassed...and frustrated and have lost all faith that any action would be ever taken against them...I feel so unheard... I have no idea how to proceed further...
