MTN Gives POOR Service

I saw this adverti*****t on your website 02 May 2019. I app**** that day for this. They phoned me but did not spoke to me, i said hello and everything but no one answered. I app**** 3 times for this deal. I only spoke to a agent now, the 3rd of June 2019. I want this deal and what customer sees customer gets. I hope you can help me, as i am a customer of MTN. The advert was for 40GB anytime data and 40GB night express data for R239 ( Sh@reLink E5573) My MTNChoice 5GB and I have the screenshot to prove it. I am VERY Disappointed in MTN.
