Bad bad service

on the 18/09/2017 i phoned in to place and order,to collect.The phone was engaged for 10 minutes constant.I eventually came through and said i would like to place an order to collect,I spoked to ida she said hold on and gave the phone to kagiso i placed my order and asked him what is the price he said R193.70.When i arrived 20 min after i phoned ,i said im there to collect my order i phoned.The cashier who is a trainee (Nancy) gave me a price of R247.50 i said how is it possible because kagiso gave me a price R193.70 they called kagiso and he said it was an estimate price he just thought of a price.The manager came and said ok it was a mistake.Ive waited another 1/2 hour for my food every time it came through the paasing window Nancy would open the package and put her finger inside.I eventually got my order and when i asked them are you sure everything is inside they said yes.I took the package,haflway i ralise the two chips was not inside the package.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
