Unable to use my number for 3 months!!! still no resolution

My prepaid number was changed to contract on 21 May 2022. The agent assisted me at Vodacom World. 3 to four days later after taking out the contract I was still not able to use my phone, making or receiving calls etc. Only to find out after cancelling my contract at Vodacom World and countless calls to the Vodacom customer care, accounts, prelegal, cancellations that the agent had put an amount of R98 on collections without my knowledge which got my account frozen. NO ONE at any of the call centres at Vodacom including the agents at Vodacom world are able till today to assist me with unlocking my account and moving it from contract status to prepaid again. Network synchronisations, manual selections, escalations and I am still not able to use my number after 3 months of this nightmare. Agents NEVER allow me to speak to a supervisor/manager even though it was requested numerous times. NO ONE at Vodacom has the ability to assist or fully understand their own processes enough to guide the customer!!!!
