Vodacom deleted my number

Vodacom deleted my business account that I have been using as a prepaid from August 2006 and as a contract from 2018. I defaulted on payments after Covid, the bill went high, the handed me to debt collectors, they suspended my number from making calls and making airtime topup, they took away caller line identity. Suddenly without any notice they deleted my number from the system, and I contacted them, they claim it cannot be brought back. I need that number for business ske, this is the number I've been using for 18 years, it's complicating my life. It has been off for 9 days now. Can anyone assist me so that I can get my number a business back. The number in question is ***
