Cancelation and refund

I've sent you an email in July 2023 after multiple failed call attempts to cancel my insurance with you. You never responded even when I requested call back. Today you debited my account for the second time and the worst part is that you blocked reversal from the bank. I'm now with Momentum and I'm paying over R300 less and over half less excess. I'm requesting that you cancel my insurance asap and refund me my money as I requested cancelation over a month ago. I will be escalating this to the ombudsman together with my initial email. The only call I'm expecting from you is confirmation of cancelation and a refund. Nothing more
