REALLY.... IS THIS CUSTOMER SERVICE???

I have been with Cell C for a number of years, I had my contract with them after 24 months expired I did not want to renew my contract as my phone was still ok. A week ago I then decided to buy myself a new phone on prepaid as I am most comfortable with prepaid, I then called the call center which then I was advised to buy a new sim card to do a sim swap I had no problem with that as my new phone required a microsim. I then had to go find a shop that will sell me a starter pack that I cant Rica, I then called them back and they told me I had the wrong sim I need to get another one, I am one person that has patients but dont give me the run around, I then got another which then after security questions were done on Saturday I was told my number and sim will be active within 4 hours. Till this morning my sim card didnt have network so I called then to ask what was happening I was told by a consultant Ayanda I need to buy another sim card as the sim swap was not done correctly. Now I have one question for Cell C whos problem is it that sim swap was not captured apparently by the system, when I did my part and answered all the question? I am deeply disappointed,wouldnt recommend Cell C
