Unsatisfied with the order and service rendered

I ordered debonairs pizza from lephalale mall and had requested or put in tripple extra mozzarella on the pizza in the order but when my order arrived the pizza was burned and the triple extra mozzarella was not added... The taste of the pizza is not the same as the standard debonairs pizza we order anywhere else...I am not satisfied with the quality of service rendered from debonairs pizza Lephalale mall, I paid R300 for a pizza that was not worth the price. Please assist me
