McDonalds delivered half of our order, twice

We experienced that our orders from McDonalds, which was 2 orders, didn't had all the items in. The first time there was a cheese burger missing. Seeing that I only ordered a cheese burger for myself, I was the only one who didn't have any food to eat when the order arrived. I then took a drive to McDonalds Tyger Manor to fetch it myself!! The 2nd time was yesterday evening. We only received the burgers and the nuggets, none of us received fries. We send this information via the app and they refunded us, BUT still, we didn't have the option to receive the rest of our food and I had to make fries myself, and by that time the burgers and nuggets were cold. Initially I asked the Mr Delivery guy to bring us the fries but he said they will charge me for another trip! WHY MUST I, WHO DIDN'T RECEIVE MY FOOD WHICH I PAID FOR, pay for the 2nd delivery if McDonalds made an error? This is not acceptable. I do not need to get my money for the fries back only, McDonalds will have to refund me for the whole meal I ordered. Unless they want to pay for the hours and frustration and petrol, and hunger, that went into this? McDonalds please contact me on ***. They are also not answering their phones.
