Repeated unauthorised debit attempts by Webafrica causing bank penalties despite written confirmation

I am extremely disappointed with Webafrica’s handling of my account and billing. I migrated from Openserve to Vumatel and was under the clear understanding that my Openserve service was cancelled when the Vumatel service was activated. Despite this, Webafrica continued to attempt debits for an Openserve service I was no longer using. After escalating the matter, I received written confirmation from Webafrica that only my Vumatel service remained active and that no further debit attempts would be made. Despite this confirmation, Webafrica has continued to attempt debits on my bank account. My bank (Standard Bank) has confirmed that there is no debit mandate visible on my account and that they cannot block these debit attempts. Each failed debit has resulted in bank penalty fees, pushing my account into a negative balance. I have repeatedly followed up via email and WhatsApp, but responses are slow or stop completely, while debit attempts continue. I am now concerned about potential collection action and the impact this may have on my credit record, despite this being a formally disputed and escalated matter. This situation has caused unnecessary financial loss, stress, and loss of trust. I am requesting: Immediate and permanent removal of all debit instructions Written confirmation that my account will not be handed to collections Reimbur*****t or credit for bank penalty fees incurred due to these unauthorised debit attempts This has gone far beyond a simple billing error and needs urgent senior intervention.
