Outsurance places **** claims on profile to increase premiums

Outsurance has increased my premiums exorbitantly based on my supposed claims over the past few years. Now that I have been shopping around I have been informed by other insurers that there are multiple claims on my profile that I have never heard of. Why have these claims been added to my profile? Is this a tactic by Outsurance to justify their high premiums? I have requested that my policy be cancelled and had to put up a fight to get it done. The consultant eventually said she would cancel it and send me the confirmation documents on email. No confirmation has been forthcoming. Outsurance cannot refuse to cancel my policy. This is highly ********* behaviour!
