Bad service with Clicks

I have placed an online order at Clicks on Black Friday. Since my order amount qualified for free delivery, I chose the delivery option. With no communication whatsoever on estimated delivery date, after 1 week I received an email to inform me of my delivery on friday the 30th Nov. I received my parcel that day. After the courier left, I noticed 2 of my items (the most expensive ones) were not in my parcel. I immediately phoned Clicks to find out what happened. The person who helped me was very friendly, but kept me on hold for more than 30mins. When she returned to the call, she told me the warehouse are aware of the situation and the guy would phone me or email me that same day. He promised.

Not a word from them. I phoned again today 3 Dec. The consultant wasn't as friendly today , after putting me on hold, she came back with the same story. Someone will contact me today, they promised.

I explained to her that we are going on holiday today, can't I maybe collect it at the store? Rudeley she said I have to wait for my email, she can't do anything. I'm still waiting for my email or any communication for that matter, and my items.
