Media24 shop - Where sre my books?

How long do I still have to wait? I ordered 2 books on 11 July 2022 as Birthday presents (Delivery 2-7 day) I emailed them, and their reply was "We apologise for the late order. We will follow up with our couriers and let you know as soon as we hear back from them." This was on 20 July 2022. I phoned yesterday too. They will get back to me. Nothing is forthcoming. Why do I have to chase them? Unacceptable service!
