No service for over a month before now no service almost every day

I called cell c this morning to complain about me always not having a network on my contract cellphone. This is not the first time I am going through this with. Last year in the early days of lockdown I stayed almost the whole stage 5 without a phone because I didn't have a phone called cell c told me that my sim card was damaged so I needed to buy another sim card with my own money wow, I then had to go through security checks after buying another sim card and I could not pass their security questions. I had to stay the whole time without a phone until there had opened. Within a year I have started going through it again like really is it a bad idea to have a cell contract. I called today the person who was assisting me could not help me, the options she asked me to activate were not there, then she said she was going escalate the call and it takes 24 hrs turn around time, with the experience I have with cell c then will not bother calling me.
