Appalling service at Superbalist online

Ordered and paid for stuff on 14 October 2019 plus an additional fee for next day delivery. Today, 16 October 2019 I still have not received my order. There's no communication from Superbalist telling me what's the reason for the delay.

When I take the initiative to call their customer care number ***, someone named Mishka answers the phone and tells me scheduled delivery is 18 October 2019 because I didn't pay for express delivery. This after I told her that I'm calling because I paid for express but still don't have my order 2 days later. She then apologises and tells me they are waiting for 1 item to arrive from somewhere but she doesn't know when it will arrive.

If it arrives on time, they'll deliver on Friday 18 October and I ask what happens if it doesn't arrive on time and she boldly says then they'll deliver later!!! This after I paid for express and got no communication about the delay and was also unable to track my order on their system.

I then ask to speak to someone who is in charge of the place and she puts me through to one Khanyi who bluntly refuses to give me her last name. This person repeats the same story and I ask if I can't then cancel that item they don't have so the rest of my stuff can be delivered and I'm told I can't!!! They have to wait for it to arrive and if it arrives on time then they'll deliver the whole order but she doesn't guarantee that they will. She tells me she can only follow up tomorrow but can't promise anything!!! Did I mention that I paid extra for next day delivery??? As things stand I'm not sure if I'll get my order, which I needed before traveling on Friday hence I paid for express delivery!

The customer service at Superbalist is none existent and I don't think I'll ever order anything from them again after this appalling experience with both their staff and none communication.
