IGNOU Query

My third year books were returned to Kolkata RC as I'm not in my hometown due to a medical emergency involving my mother. Someone from IGNOU called me yesterday and said they will send it back to Delhi within 7 days as they have no provision of keeping the books in Kolkata RC. Asked me send someone on my behalf with my ID card to recieve the books.

Can someone please help me? Picking up the books from Kolkata office and holding it until we return?
