Unhappy with lack of communication

I took out a wear and tear policy with Innovation for my Toyota. The agent promised me that I would be able to claim from policy immediately, without waiting for the 3 month waiting period, if I paid for three months upfront. He also quoted me a different amount than what was stated on my policy documents.

I queried this with a customer service agent who then promised that this would be investigated. And I have yet to receive feedback. They keep calling me outside of office hours, the phone rings for like a second, giving me no opportunity to answer the call and then I can't call back because its outside of office hours. So the call cuts.

It's ridiculous.

I have emailed them because I want to cancel this policy due to the lack of professionalism. I need a response.
