McDonald's Umhlanga worst store ever

We ordered 3 Big Mac, 1 Large chips and a kiddies meal on the Uber Eats App. We were only sent 1 big mac burger, cold chips and the kiddies meal. When we called the driver Thierry back, he told us to call McDonald's Umhlanga, have been trying them for the last hour and a half and the line is busy which I suspect they've taken off the hook. This is the second incident with this store, a bunch of rogues who cannot be trusted.
