Kfc Zambezi Junction

I had a bad experience at kfc Zambezi junction where I ordered three lunchbox meals which were displayed as R70 each on the screen,but ended up paying way more because a cashier decided that my order will be medium without consulting me. When I asked how did we reach to a total of two hundred and fifty something instead of R210,she looked bored and impatient,then called two more cashiers and I was told “customers confuse sizes of the meals and instead they are short of R3,they gave me more change” they took out a calculator and started calculating,emphasizing that,that’s the size I ordered and it’s price,making me look stupid as if I didn’t know what I have ordered. My order number was 388.
