Innovation refuses to cancel my cover and provide me with my refund

Innovation group is refusing to cancel my policies that I have with them despite advising them with numerous phone calls that my vehicle has been sold! I have spoke to over 10 consultants since 31 July 2024 and sent over 20 emails with no response. From Mphiwe to Buhle, Simon, i have even spoken to a Komotso who promised to be a manager advising the urgency of my cancellation with a 45 minute call but still no follow up as promised. I need feedback..it's so simple, I mean is this not what I was supposed to receive as a paying customer. All I need is my pre-owned warranty, service plan and tyre and rim cover to be cancel and a refund to be done to my bank account as I no longer have my vehicle. What else should I be doing ? I've called, sent emails, promises were made and not delivered...the next step is surely the ombudsman as a customer cannot be ignored.
