Impossible to cancel Outsurance policy from abroad

I live abroad and am trying to cancel a car insurance policy I took out on behalf of my daughter. It has been impossible since 0800 don't work from abroad while they responded to an online request by sending me confirmation of the current policy via a no-reply email. My daughter tried cancelling and after a 35 minute process was advised only i could. All other routes of failed including an international number they provide which goes unanswered. In the meantime I have now been billed for another month. So easy to sign up and impossible to cancel. ********* and *********** in equal measure. The Hello Peter only allows me to enter a SA cell number but Outsurance if you do bother to read this the number does not work and I should be contacted via my Gmail address.
