Pathetic Service delivery

I bought a Math Excellence book on 27/02/23 including delivery just to find out that the book and packaging will take between 2-4 days. When I called back the next day 28 Feb the girl informed me the invoice was not ready so the book cannot be dispatched and it will take about a few days. I then informed her that I will collect the book because my son requires the book urgently for school. When I picked up the book 01/03/23 I was informed according to company rules I cannot get my delivery money wich i have paid for back. Life is already so expensive here petrol went up again . This is unexceptable. Firstly they don't have a cooking clue how to work with clients. If I knew I would have gotten this service I would never used Caxton Books. I will inform my son's school about this pathetic service deliver.
