Cell C - Missing application and Run around

I app**** online for a sim only deal and was called by someone from Cell C on Thursday 17/01/2019 to confirm that my application was successful and that my sim would be delivered Friday 18/01/2019. It did not arrive, so I called Cell C to find out where my sim was on Monday 21/01/2019 and was advised that it would be put out for delivery on Tuesday 22/01/2019. Once again the sim was not delivered, so I called in again to find out what the issue is. Firstly, I called in to the dispatch department who couldn't find my application and was told I need to speak to the sales department and do a new application. Go through to the sales department and get told I need to go through to the dispatch department, as they can't access the information required. I go back to the dispatch department only to get told I need to go back to the sales department. An absolute waste of my time, having to verify my details 3 times, only to be told that the dispatch department will email the online orders department to contact me or that I can contact them. How does half of Cell C know that my application exists, but the other half can't find it? I spoke to dispatch Monday and my application was there, then spoke to dispatch Tuesday and my application does not exist...this after having someone from Cell C call to confirm that my application was successful. Highly disappointed in this poor service
