KIT KAT Cash n Carry bad service and overpricing.

Benoni Kit Kat invited me as a traders to buy stock in bulk and even offered me a Kit Kat card which will classify me as a trader but they charge us like I'm buying the stock to eat....they have been charging me 500g×25 selati for R209 while the rest of all Cash n Carries(Benoni Cash n Carry, LAS Vegas Cash n Carry,Poer Trader etc) they all sell it between R182-R189, in other words they want me to overcharge my clients by their pricing as I have to use the same receipt to do my own pricing, again the price of polish which sells for R219.99×25 they charge me R269,their prices are so unreasonable but they claim to be the best, can the Competition Commission please look at their prices and what makes them to overcharge me Paul Mathe(BEN111531)

Again today they charged me a transport fee of R150 to deliver my stock but they left a 20L oil behind which I paid for it and it's on the same receipt which they used to release the other stock and when call to complain they say I must come and fetch it.... I am really looking forward to do busness with them but their service keeps getting worse day by day from the day I started buying stick from them.
