Don't order online - No delivery on orders

I ordered some books on the 13th of July 2021, and estimated delivery day was last week 26 July. I tried contacting the call centre to follow up on my order on the 27th of July as I have not received any notifications of delivery. There was no answer on the *** number. I then proceeded to send an enquiry via email to *** to which I got a ticket number and that an agent will call me shortly. NO ONE has been in contact with me since. I have tried following up with the store where the order is supposed to be delivered to on the 27th, 29th, and 30th of July and 2 August, but they can't help until the order is delivered. I even tried phoning the head office number *** and the receptionist just transfers me to a number that rings and then cuts off.

How can a company not give ANY feedback to their customers??

The lack of service is shocking to say the least.
