Bookshop Of India — Book Paid For but not received

Address:

71 Sunshine, Dr. R Patel Lane, Opposite Breach Candy Hospital

I had ordered a book on the 29th of October through https://www.bookshopofindia.com/.

My order number is 74327.

I have paid Rs. 645 against it. However, I have not received the book (the 4 days for delivery have passed). There seems to be no way of contacting the book shop.
