Bizarre incident with Mochachos Sunninghill

So I ordered from Mochachos Sunninghill via UberEats - ordered 2 double cheese pine burgers, both with chips and Coke. What they send is one single cheeseburger, one single pine burger and just one Coke and chips.

I phone them to complain about my order, it is quite different from what I ordered. They say they will correct it.

My expection was that they would send us at least new burgers with a chips and Coke.

They literally send us one slice of cheese, one slice of pineapple, the 2 missing patties and a chips and Coke.

My entire family was quite stunned by then literally sending us only the the missing items!
