Delhivery — I'm complaining about my delayed order

I have had ordered two manga books from bookswagon 1 book has reached to me before due date but one still hasn't come. The tracking number provided by Bookswagon shows that my book is in transit under Delhivery and would have been delivered today as of 24 August 2022, between 12-3pm but its past 3pm now and no text, calls or any updates about my order. It still shows my order is in transit even when today is the delivery date. I kindly request you to Please look into my matter and deliver my book asap, I have already paid for that book.
