False and ********* marketing

I have had multiple bad experiences with Takealot but I continued believing their false marketing but this time I am highly upset due to the fact that I reached out to their customer service and received a generic response which did not even address my issue and was also insulting. Takealot advertised a cyber Monday deal on a PlayStation 5 for R7999 and dropped a discount count on social media to claim this, valid for the first 50 customers. Everything was fine right up until just before I made payment - I was in the process of making payment for my order when I noticed the incorrect amount which was R9290 and not R7999. As a result I canceled my order and went back to see why this happened, only to notice that in this process of checking out, the price was changed from R11999 to R13290 and the discount deducted R4000 hence the reason for the incorrect price which if I had not noticed, I would have completed my payment at the incorrect price. This is so wrong and deceiving. I reached out to the CGSO and this is valid to be escalated as I reached out to customer service to assist with resolving this and I was told that there was no error in the screenshot I provided and that it’s too bad I missed out on the deal. I have never received such poor customer service from anyone else and I will rather take my business elsewhere even if it means having to pay more for things rather than to continuously be **** to and deceived by Takealot.
