Food item missing from delivery

I placed an order yesterday on uber eats with Fishaways Mall of Africa. Ordered the family platter, squiggly pops and pop prawns. However, when the food was delivered I noticed that the family platter was missing the calamari strips that the menu says its has. How can you be expected to pay for food but not get the correct order delivered. This was obviously the fault of the restaurant as everything else in the order was there. This is totally unacceptable and not at all the standard I am used to of Fishaways. Very disappointed!! I did complain soon as I realized on uber eats app but no one has responded. Loyal customers shouldn't be treated this way. Especially if we pay with our own hard earned money.
