Old/rotten Avocado on Pizza Hut order.

I bought the 2 box meal with 1.5l coke for R120 Food arrived late Rotten/old Avo was on the one Pizza (I'll post pics on social media If I cannot post here) Food was dry and tasteless. (Probably because it was late) Ordered a coke but they brought cream soda. Driver told me they didn't have coke. Why was I not contacted to ask if it could be replaced? I used the Mr D app to place the order. Branch responsible was the one on the Bluff, Durban, South Africa. (Bluff shopping center)
