Express/ Service?? Don't think so

I would like to express my displeasure with the service I received from Van Schaik Bookstore Online service.

On the 16th December 2018 I ordered textbooks online with the express option. Textbooks (not all of them) were only received on the 2 January 2019 (Courier called asking if we can meet half way, we refused and the books were delivered around 18:00) - and during the time I was the one making follow ups - I was not alerted or notified that textbooks would not be delivered in the 3 days stated with the express option, I was also not informed that not all textbooks would be delivered.

Today is the 09 January 2019, and there are still textbooks outstanding. I am still not notified, when I call in I am told that the "supervisor" was supposed to call me on Monday. They are unclear as to when the outstanding books will be delivered.

I paid for express, I paid for service, I am getting neither.
