Mac delivery never delivered my meal!!!

I ordered on the Mac delivery app on the 19th June a large Mac feast meal and I paid online and my food was never delivered. But when I tracked my order it showed that my meal was delivered when in actual fact I never received my meal. This is very disheartening and dissapointing that someone kept my food for themselves. Please investigate who the driver was and who he gave my food to as it never arrived at my house.How do we trust Mac delivery and pay online when you don't get your food. I want my meal or a refund please.
