Misrepresented Price.

On the 26th October 2020 I purchased a shower for R3999. As an ordinary person I saw the price as advertised and paid immediately. My builder collected the items purchased. To my surprise I was informed by my builder today 2020.11.11 that it was not a complete shower but only the shower door. I viewed my photo that I took and saw that there was no other price on the side glass which indicated to me that I had to buy it or it came separately. I went to CTM Worcester today and was told by the consultant which assisted me that the price of R1699 was placed today on the side door. I was furious that they have misrepresented the item as no one indicated sold separately. What tipped the scale was that when the manager was called he indicated that he is at the mall. As a customer I feel aggrieved in that I was not explained from the on set what I will be paying for or advised further on my purchase. I'm furious as I had to drive 120km in total to hear that the manager is at the mall and me as the client must don't even get an ear to voice my unhappiness. I have the photo of the 26th which shows that there was no price on the side glass.
