Not a happy Cell C customer

I did an upgrade on 3 March 2023, my order SPI***5 was approved on 9 March 2023. In the next week I did not get any feedback and called Cell C again. I was promised that my new phone will be delivered before the end of that week. The next day I called again and was told that my order is on hold as they do not have the color that I requested. I never requested a color but black and was told from the beginning that they had stock. The redid my order as they have to change the color and here we are a week later again and still nothing. I sent emails, no response. I call and being transferred to delivery department and hold for more than 30 min without getting through. I am a customer of Cell C for many years but is really disappointed in the services that I received.
