Worst experience of my entire career to lose so much business

I had the worst experience with Vodacom since I’ve had my number from 2007 up to 18 February 2021 where my number suddenly stopped working and I visited the branch Given a ticket S105 at time 10:16. I was put through to customer Where I was informed that my number has been deleted from their system and that I cannot get it back ever again. My frustration is that the number is one that I use for my business and to change numbers suddenly I will lose a huge chunk of my customer base. I find this service extremely unacceptable and I will port my second number to a different network to avoid any further loses in future.
