Rude poor service

On the 26 May 20 we went to Festival Mall Kempton Park. Intention was to purchase a explorer decoder but needed information on the difference between explorer 2 & the new 3A model. Phew! the gentleman who is working on the DSTV stall was so agited as we asked what the difference is between the 2 he has on his display he could not explain even one which was the latest. He simply said rudely its new! We realized he lack product knowledge cause of his ride and surely expressed how much he hate what he is doing. We left and had to do research and came back 29 May and he was then worse as we now wanted to ask questions based on findings the other does not display time. We then decided to enter their shop and found assistance from his colleague who is knowledgeable and he explained all we needed to know as we buy. I requested his name and acknowledge his assistance as we appreciated we asked the name and he started to tell us he was uncomfortable.I then requested to kindly speak to the manager. Upon explain he also refuse to give the name and I told him I didn't understand why they have product knowledge which their consultant who's *********** and rude.They finally gave us the name Phinias Dziwiri which was just to dismiss us I am certain Multichoice is not aware of such doggy outlets with *********** people denting the Multichoice Name as a result we couldn't make the explorer from them. The manager said he was Rudwell whom I am not sure if it's true as they were hiding something...
