Prepaid to contract dispute.

I disputed a prepaid number being converted to a contract number without my consent & now I am expected to pay an account which I did not ask or consent to. After my complaint at the same store with a similar discrepancy a few years ago I complaint again & wrote to the ceo.vodacom.co.za. on 31 March 2026. On the same day I received a reference number *** informing me that the complaint is close, however when enquiring via Vodacom on their 082135 number I was advised by the agent to visit the store they will have more information for me, however I visited two other stores as well as the store where the problem happened & nobody could help me. No one can explain to me, what does the "complaint has been closed" mean, on their C3D system there is no information & nobody can help me. Currently my Vodacom services are suspended & in their(Vodacom) opinion my account are in arrears which is not due to my own fault & I am just expected to pay what is due. How is it possible that a 61 yr old pensioner are forced to run himself into future financial difficulty & distress when everyday people are cautious as to wasteful expenditure one cannot afford.
