Cancellation Requested almost a year ago, and zero response

I requested someone contact me on 23 March 2021 to cancel my Gap Cover, as it is not required, and I cannot afford the installments. They are also debiting more than what my policy document states. I received an automated email with a reference number (***) advising someone would contact me in 48 hours, and yet it has been 9 months later, no contact from the institution, and the debit order are still going off my account! This is very poor customer service on their behalf. I have called their contact center number, but the calls are never answered, it rings and goes dead. I now have a new request number (***2)

I need URGENT cancellation on this Gap Cover please.
