Misleading False Advertising

I wanted to upgrade my cellphone contract to the P30 Lite, Went to the Telkom website which shows they have the 1GB contract for R300 pm with an additional 5GB of data for 24 months. I called the Telkom store to reserve my phone and deal and they advised that this was a Black Friday Deal and they add is still on the site. There is no where in the ad does it say Black Friday deal. Very disappointed and misleading
