McDonald's Woodlands are ******!!

I have ordered a double quarter pounder burger MEAL and n chicken burger MEAL through the drive-in. When I wanted to pay they told me sorry they don't have any cooldrinks to give me with the meal. I've told them it is OK but then I will not pay for the full meal, because the price of the meal includes the burger, chips and a 500ml coodrink. Then they've told me they can't do it and will give me 200ml juices. But I've ended up paying for the juices aswell when I've got the slip. So I've ended up paying for a full meal without the 500ml cooldrinks and I've paid for the 200ml Juices extra. This is unacceptable and ****************!!
