Steers Bluwaterbay Service

I ordered 2 King Cheesy Bacon meals this afternoon, they advised of a delayed delivery of about an hour due to not having enough drivers, the order was delivered but was the incorrect order, it was not the king burgers I had ordered. Instead a received two dry burgers with one slice of cheese and bacon with absolutely no sauce. I called them back and was advised that the correct items would be delivered and the incorrect order collected, I waited over two hours for that order that never arrived when I called them to follow up they advised of a driver who was on the way but stuck in traffic, 20 minutes passed and I called again only to be told that the driver was not picking up the phone. The manager told me that she would try calling again and call me back. I was instead called back by a guy who tried smooth talking the situation by speaking to me in IsiXhosa and telling me that the driver was stuck on the highway and that I should go to them in Bluewaterbay, at this point I had verbalized multiple times on the call that wasn't an option and I'm unavailable tomorrow for the proposed time for delivery. He kept insisting and started shouting back at me on the phone asking me what I wanted him to do also refusing to assist with a refund. I just called them back to get the manager's details and owner of the store and the lady who picked up the phone refused to provide those details to me, advising me of how busy they were and that the manager was at debonairs and dropped the phone on me. I'm beyond livid and will be taking this further. This is the worse service I have ever received in my entire life and will not take it lying down especially because I paid for this order that no one is taking seriously. The lack of respect for customer's and their time and audacity to shout at customer's by the staff is absolutely disgusting.
