Can't cancel policy

For over 3 weeks I've been trying to cancel a policy with clientele but nothing, I get little tobhrl at all the only time someone got it in touch with me which was last month told me they "can't cancel the policy since its not their department" but has never gotten in touch with.

Have sent numerous emails and follow ups.

Eventually on Monday the 2nd of October when calling into the call center I was sent pillar to post. Got passed to about 6 call centre agents only after throwing a tantrum was I told that there is no one from the retention department and a query would be logged someone the department would get in touch with me in no more than 24 hours but it's been more than 48 and still haven't been contacted
