Incorrect delivery

Called to place a order for Nandos 3 meals the order arrived there is only one meal and 3 cold drinks i send the order back. I call again speak to the same person but this time i update my order which is 5 meals now. The order arrives again there is only 3 meals. I do not know who does not listen or cannot read but the service sucks. I would suggest you close down as no on can follow orders.
