FNB Warranty Policy

I have had a motor warranty plan with FNB since April 2019 and bought a new car a few weeks ago which is under warranty and I called in to cancel the premium today and was told by Tshepiso that they could not refund this month's premium as the system has automatically scheduled the collection. I think this is unfair as this vehicle has not been in my possession for a while and that I should be refunded this month's premium. I acknowledge that I left it a bit late to cancel but I have not made a single claim since I signed up for the policy.
