Sim swap disaster

I need management to look into this and fix it. My phone was ****** on the 21st of June, I called to block the phone so I can get the black listing number for the police and insurance( I forgot what its called). Security was passed and agent said to wait 48hrs and someone would reach out, someone from the blacklisting team called the following day but unfortunately couldn't reach me. I called back and was told to wait. Called the following day and was told the case was closed and I had to start Security from scratch which I did but this time around I failed. I tried the next day and same thing happened even went to cell c but they couldn't help me, I think eventually on the Tuesday it went through now I was told for sim swap I've been blocked and I must try in 30 days. Waited the 30 days and called in, answered the same questions but still failed. I have been using that number for more than 5 years and almost everything of mine is linked to it. I want to know from Cell c, I was able to pass verification twice when doing the black listing but the same questions are failed when trying to do a sim swap. This is ridiculous, I need the number back and I need it to be fixed so I can use it again
