Horrifyingly Terrible Experience (Depressing Customer Service)

I don't even know where to start.

A laptop was ordered for work. It was through one of there 3rd party companies. Upon inquiring on the ETA for delivery, I was informed that the supplier never delivered the laptop to the Warehouse and that the fault lies with them. That's it.

I then contacted the Supplier who then stated that the laptop was delivered and received a week earlier at their Warehouse (confirmed by the Courier Guy reference and Takealot Seller screenshot). I then informed Takealot who then changed the story and said that they will escalate the issue and get back to me. It has been 2 weeks. Absolutely no update gets provided and I phoned back every day. Dealing with the Team Leader Rabia G. has been horrifyingly terrible. She only has nice words with absolutely no substance. I now proceed to phone back each day (as no updates are provided since the previous call as I am promised an update each day - even if just to acknowledge that there is no progress). The supplier has gotten in contact with Seller Support who inform them that the laptop has been found and as it was a counting error at the Warehouse. My contact at Takealot knows nothing of this.

I don't know what to do. I do not know who to contact at Takealot and I am stuck. This has created unnecessary anxiety and stress and now it appears I must escalate the issue on my side.

We are all waiting patiently for Amazon to arrive in South Africa to humble Takealot once and for all.
