old appalling horrid food they charge R97 per portion for??

I ordered food Saturday on the Mr Delivery app. In total it costed R400 for 2 people, i dont mind paying for food if its a good quality. The Chinese arived, which was supposed to be sweet snd sour pork. We received no sweet and sour sauce, it was old hard and ice cold pork mini *****. My dogs didn't even wanted to eat it. I immediately called Mr Delivery but they not answering any cslls at this stage. Tgen i took photos of the appalling horrid things they want to tell me is food and i emailed them regarding my complaint and demanding my money back. Well with no surprise no one has contacted me, nor is the issue resolved. I spend a lot of money on the Mr Delivery app and i expect my queries to be attended to just as quickly as they take my money!!
