Cell C's poor customer service

I took a new double deal contract with Cell C and 1 of the phones was not working and called them to collect it and they did and was told I will be getting a replacement phone since that one could not be repaired. This was 2 months back and after countless attempts I still have not received a phone and then last month i was told the Samsung A32 is discontinued and they will offer me a new phone which hasn't happened up until today. I am really not happy with the services I am getting as when you call the customer care you get transferred from one department to the next. I even went to a Cell C store to try and get help but they couldn't help me. I am now paying for 2 phones but I have one. I've never been so disappointed by a service provider in my life and can't even do anything about it
