Mr Delivery false advertising

This people are the the biggest ***** there app states menus that is incorrect and ********** to there customers. I placed an order for 4 hake fillets large chips onion rings 2 coleslaw for R178.90 according to there app in actual fact it is only 2 hake fillets. Started phoning since 15h35 to complain my order was wrong till last night 21h45 and stil no order after 5 attempts. The manager at the call center then told me she will sort it out and still nothing but I must phone today they will sort my food for dinner tonight. Phoned them and then they Wan to retract there promises made and still no food do not trust this menus on the app as they know about the problem but nothing gets done because most people don't want to make waves. I am going to go to newspapers and ombudsman for false advertising as I have the screeches of how much time I had spend on the phone the menu from the app and still no correct order
