Poor service Pizza Hut Rivonia and Mr D

If I could give this store a negative rating it would be - 10. I have had problems the last four times I've placed an order with them via Mr D App. First time they gave me a pizza with a thick base when I asked for thin. Second time I paid for extra olives and was not given extra olives. Fourth time I ordered a veg pizza and received a meat *****s pizza with beef and pork which i don't eat for religious reasons. When I logged a query I was only partially refunded. Today I placed an order only to have it cancelled two hours later. Between Mr D and Pizza Hut Rivonia the service delivery is awful. After being a loyal customer for years I will not be ordering from either ever again. Pizza Hut Rivonia and Mr D you have left a bad taste in my mouth.
