Bad service and coverage of Cell-C

I have been a customer of Cell-C for more than 15years but with the poor service and non coverage that is a constant issue leaves one disdain. I have a contract with them where I pay more than R2500.00 a month and for the past 2 weeks my phone loses network and had to restart it for 6 to 7 times at a time before network comes back again. Then yesterday the network didn't come back at all, I do not have that LTE or 3G showing on the top right of my corner. I called the customer service and they sent me the wrong settings on how to do a setup of my phone but didn't even work and the steps were even wrong and confirmed by the sales consultant at Rosebank. I ended up going to Rosebank mall, driving from Randburg to Rosebank for this to be fixed. It was fixed within 5 minutes and I was told that there is no specific problem but at times the network becomes unstable especially with iPhone 14 which I find it hard to believe because I have been using this phone for almost 23 months now. When I got to Randburg again, the issue came back and as I am writing this I do not have network, coverage and called the customer care and was given the same wrong instructions and that I must take my sim card out and put it on another phone and see if the problem is going to persist. Which other phone, because I wouldn't bother if I had a spare phone to use. Now I have to drive again and go to their branch for the 2nd time, using my petrol for the same issue within a space of less than 24 hours.
