CANCELATION OF SERVICE/USELESS CLIENT SERVICE

I have had numerous discussions via mail/phone from 23 December 2021 with Vox with regards to the internet I am receiving and the subsequent cancelation of my service. On 05 January 2022, we agreed that the service will be canceled at no cost to me. I followed this up with the Cancellation Department and had no feedback since. I did not use the service during this time but today the debit order for a service that was canceled went off my account. How in the world is this possible!!!!!
