ADT Fidelity Security Group keeps taking money for services that no longer provided

On the 28 March 2023 ADT Fidelity Security Group's Customer Service Agent Accounts Level II Nandipha Tshangela informed me in writing: "Your cancellation request will be processed and service will expire on the 31st March 2023." However, on the 31st March 2023, ADT still debited my bank account a monthly payment of R372.70 for service that no longer exists. This the debit order is not authorized by me. It is not legal. More to this, because I was not provided with communication that I would be further debited end of month, or that there would be any charges, a debit order was processed to my bank account without my knowledge and consent. My communication with the "Customer Service Agent Accounts Level II" via email is not answered. I recommend everyone to avoid this dysfunctional company and file a complaint with the Office of the Consumer Goods and Services Ombud (CGSO) should a successful resolution of your abused consumer rights prove to be impossible with the company.
