*********** and bad service

last night the 16/02/15 i went to this branch to order a pizza . i orderd the double deal meal for R99.90 when i placed my order i told them i am a diabetic so i can not have a coke that comes with the meal so i asked for a coke light or somthing the same the server said they dont have coke light in a 1 lt but i can have another flavour so i told her AGAIN that i can not have coke etc so i asked if i could get 2x 500ml coke lights instead after a discussion amongst them selfs and a lot of confusion they told me no they cant do that when i asked why not they just said they cant .None of them had any idea what they were doing when you place your order you must repest urself over and over .I feel if they are having a item like this then they should cater for everyones needs . I did not place my order and i walked out they will not see me again
