Late delivery

I have sent a parcel to be delivered at Amravati (Maharastra) on 3rd Aug, I was informed that it will be done in 2-3 days, however today is 11th AUg and still there is no update on its delivery.

The courier Number is 210810609 done from Malviya Nagar, Delhi

Any update on this will be highly appreciated.

Thanks and regards
