Dont buy their promotional deals, you wont receive your items

I purchased 2 samsung s23's from the samsung store in clearwater mall. As part of the promotion i saved R10,000 each phone and was suppose to receive 2x samsung s6 lite tablets after registering. Once registered to receive the tablets it says 7 to 14 working days via an email you receive. It has been a month now with no communication or anything from samsung. I phoned in to find out whats going on with the shipment of my devices to find out theres a stock shortage in south africa and I will need to wait for device to be shipped in and theres also a backlog. This is unacceptable, not receiving an update and then for samsung to make their issues mine. Dont promote an item if you cant backup the stock to support it. The consultant I spoke to was also not helpful at all, even asking to escalate the issue to management, he just repeated himself over and over with the same story. I want either compensation such as the cash value pay out for the tablets or something else as a replacement such as 2 samsung watches or so forth. I dont feel its fair for samsung to make it my problem that theres no stock as well as myself suffering a loss in value for the tablets due to the delay, as my plan was to sell them to drop my cost of the phones.
