Online order gone wrong. No delivery yet

I write with such disappointment. On 29 November 2019 I placed an order - Order *** which has not been received by me to date. Game's delivery promise is 7-10 working days.

On 8 December I received an email notification of my order being dispatched for delivery and your courier partner will contact me with further tracking info, however no contact has been made on all contact numbers provided to this day.

On 18 December I received delivery confirmation email of item not received, which I queried via email with no response.

Kindly confirm who received the order? At which address? What time ? Who signed it off? I need proof of all that! Which courier company was used and what is the tracking number? Who delivered? You could not have delivered to me without contacting me first, you will have no entry to the premises. So no delivery to me could have taken place.

I am getting worried as the order is taking too long to arrive. I ordered well in advance so that by this time the item will be with me.

Can this be resolved ASAP . It had said 7 -10 days to deliver, which has long lapsed as it stands.

Please advise where in Centurion or Roodepoort I can go to physically collect the said item myself as the online thing doesn't meet its promise.
