Poor quality control on food

I ordered a few pizza's on Friday night via Mr Delivery from Pizza Perfect Garsfontein as a special treat for me and my kids and my pizza, a Miami, which is fairly expensive, arrived with no avo which is the most expensive part of the pizza. I tried logging the issue twice on the Mr D app however their app did not forward them the pictures and did not store them on my phone. Either way, where is your quality control? Why don't you check your orders before they go. It quite ruined what was supposed to be a special night. I can't afford pizza more than once a month and this is the disappointment I have to deal with, with my children as a single mother and a single source of income. I'm terribly distressed by this and will not be ordering from that branch again. Ever. Nor via Mr D.
