Erroneous Billing and Harassment Following Policy cancellation

Vodacom Complaints Department, I am writing to formally complain regarding the severe and ongoing administrative error concerning my insurance policy, which I successfully cancelled on August 26, 2025. On the date of cancellation, I was explicitly advised by your representative that my account was in good standing and that I owed nothing. I subsequently received an SMS confirmation that my policy had been "cancelled successfully." Despite this, I was billed the full amount of R305.75 on the very same day. I am now being harassed by automated SMS messages stating my account is in arrears and demanding I make a payment arrangement. When I contacted your accounts department, the service consultant claimed she was unaware of how the account was cancelled while owing a balance. This is an internal administrative failure, not a debt owed by me. I demand that you: Immediately reverse the erroneous charge of R305.75 Permanently remove any false "arrears" status from my account. Cease all collection SMSs and harassment immediately. Provide me with written confirmation that this matter has been resolved and my account is closed with a zero balance and under no circumstances will I be harassed by Vodacom. This error and the subsequent harassment are utterly unacceptable. I expect this to be resolved within 48 hours. I look forward to your urgent resolution.
