Worst triple derker

Yesterday the 22 November, I had sent my husband to buy triple Derker at Debonairs Hillbrow branch, we Normally buy It and never complained but last night was the worst pizza ever the triple layer looked as if it was single as it did not contain much filling you could count the meat that was in between and they just threw in lots of mushrooms it was soo thin, I have called the manager on shift and all I could get from her was my husband must check next time he buy to avoid it from happening again, I told her we cannot pay soo much money for what we have received yesterday and she just said they are sorry, I am not happy at all.
