Sim swap nightmare

I cannot get a sim swap because of a difference between my bank statement and what CellC says the amount of my last recharge was. Having been ****** my life has been a nightmare, I need my number to survive as it is the number my clients know but Cell C is refusing to issue. With the pandemic, one cannot get an ID until level 2, I went to them carrying a very clear copy that was recently certified but they didn't want to help and said I must use the call centre and that as well went south because my bank statement and their systems clash because of an amount they deducted upon my last recharge. Now the only option I have to getting my number back is to port to another network. I have been with the network for more than 8 years and have been happy. So disappointed.
