Oneplan pet, worst experience with and a pet insurer.

Probably the worst experience with an insurer, first I stated to the agent who offered me the policy- exactly what I was looking and what I needed to be covered. He offered me a policy and I thought the premium was quite low but he stated it covered what I needed, only to find out, when I used it- that it was not at all what I needed. I requested a call back to firstly upgrade the policy and add more animals, waited for days for a call back. When someone did get back to, I requested a schedule be sent to me, which she said would be- this never happened. I then have been trying to cancel the policy for what feels like forever, only to be told to sent an email to the cancelation department and an agent will then get back to me. Once again a waiting game, and finally someone calls me today, only to try and sell me additional policies. I asked to be transferred to a department that can cancel my policy. Finally get through, only to have the phone put down on me!! I have tried calling, I have whatsapp, I have spoken to agents on the app and still nothing is done!! I want this policy cancelled!
