Utterly disgusting service from cell c

I have been a cell c customer for 16 years, I have 2 contracts on my name, last week Michele phoned to upgrade my contract which I haven't done for a long time as I was happy with my phone, she wanted to upgrade me with 2 new phones anA34 and A24 Samsung, I told her I didn't need a new phone let alone 2,she told me to sell the second one, I also told her to then upgrade my second contract with a S21 Samsung, she agreed, my phones arrived and not the other Samsung, only to find out that it was discontinued, which they did not inform me, I changed it to another phone, ever since I got the A 34 it was giving me problems of connecting to wifi even if I was right next to the router, I tried everything, resetting the router, restarting and resetting the phone, but nothing worked, I finally called cell c to complain about it and to return the phone for another device, which took forever to get hold of the proper department and many calls to them because I was constantly being transferred and cut off, making me go through the process of verification upteen times which frustrated me beyond, I received a case number for them to pick up the phones, I call the next day to find out about the case an when they were going to pick up, I also wanted to know about other devices that I could rather take, this morning I received a message to say they will pick up the phone to repair which is not what I asked them for, i called again to rectify this and requested the agent cancel the A34 and A 24,because I now realize that the just wanted to get rid of these useless phones, I am really disappointed and upset with the service from this company, I told the agent if my request is not resolved to my satisfaction, I will be canceling both contracts, and taking them to the consumer council and icasa, why should I pay for a faulty, useless phone, utterly disgusted.
