this is inform you that the parcel of above consinment number by speed post was dispatched from banasthali on 16/05/2020
and reached faridabad at 23/06/2020 but it is showing in the website of india post that it has been reached at faridabad on 23/05/2020 . The admission of a child was not accepted in banasthali vidyapith due to late delivery of that parcel which contains precious document as a result it affected the future of my child . Speed post take more than a month to deliver the courier and also not uploaded on in website.
I want that it should be updated and also need a confirmation letter by india post that the details are updated in my email id - [protected]@yahoo.Com so that we can send that letter to banasthali for the admission .
