Pathetic service - Items missing from order

Unfortunately, I have received nothing but the worst service from Order in. On Tuesday I ordered food and there were 2 items missing from my order. I confirmed with the delivery guy that it was in fact missing. I then emailed advising them of the error. The delivery guy should confirm that all that the customer ordered is there. Then i received a response saying that I will receive my missing Items Thursday, as i requested. I mailed the Faye, she was on leave, spoke to Mtutuzeli and i forwarded my emails from Faye to him. Then i received an email from Shana stating order is on its way. When i specifically said i want it by 13:50. If these people can read emails or liaise with the customer before making stupid decisions then the world would be a better place - literally. Service is the worst i have ever come across and every single time i order using their service, its wrong, late or something. Hire more competent staff because you are very far from having a world class status let alone a national one.
