Deleted number for no reason!

Vodacom have deleted my number that I have been using for about 12 years. After a payment was made. I have been to various Vodacom stores and been on the line for hours on several days trying to get to the bottom of it. It is unacceptable and I’m losing work without my cell number. I can’t do my internet banking because I cannot receive an OTP or anything. This is completely unacceptable and I’m desperately trying to rectify the situation. I have tried everything from customer care to Vodacom legal department. I need help. My business relies on my cellphone and my number.
