Deliveryxtreme dissatisfaction

Very dissatisfied with the deliveryxtreme in sandton. I ordered a classic chicken burger from steers the lady insisted that there was only beef burgers on the menu I clearly srated that i wanted the classic chicken burger combo which on the menu was R56 . They brought me a beef burger with the electronic receipt saying classic beef (chicken).costing R70. so unhappy with the outdated prices on their menu and poor service delivery .
