Feeleing let down by Supaquik Witkoppen

I was there at Supaquik Witkoppen for replacing Brake Pads for my Kia Cerato. I was told by Mr Paul that it will be R1700 with all parts and labour, When i asked for a discount I was told he can make it R1500 and I was specifically told that FERODO brake pads will be put. However When i bring the car back home, I realize that LMB Brake pads were put. This was never informed to me. For LMB Brake pads I already got a cheaper quote from Tyres and More. However I wanted to put only FERODO / ATE Brake pads for my car. I feel cheated and dejected by this service. Please take note. When i called the store I am being informed that Just because I wanted a Discount they put LMB Brake pads( without informing me). This is unfair.
