Poor service/Non service and failure to cancel policy after several requests

Email sent on 29 August 2022 with cancellation letter for Priceless home owners policy to ***, ***, *** and ***. No acknowledgment email received up to now. 26 September 2022, Momentum debit order again went off my bank account, after several emails, still no feedback, no acknowledgement, no refund. This is a major reason why I've decided to cancel the policy, as communication and interaction with me as policy holder is very slow or non existent. I am still waiting for the debit order for 26 September to be reversed and my account refunded, I am still waiting for acknowledgement the policy is cancelled. Very frustrating
