Unacceptable and disrespectful handling of a simple cancellation

I emailed OUTsurance this morning requesting the immediate cancellation of my policy. I have since phoned three times trying to get the matter resolved, only to be left on hold listening to music instead of receiving assistance. When I have managed to speak to someone, I have made it very clear that my decision to cancel is final and not open for discussion. Despite this, I have been subjected to unnecessary small talk and attempts to prolong the conversation rather than simply actioning my request. I find this extremely disrespectful and frustrating. A customer should not have to repeatedly call, sit on hold and explain that they do not wish to debate their decision simply to cancel an insurance policy. I am not asking for a sales discussion, retention exercise or further explanation of my options. I am instructing OUTsurance to cancel my policy. Please process the cancellation immediately, provide written confirmation, and confirm that no further premiums will be deducted. This should be a straightforward administrative request, not an endurance test.
