THE WORST SERVICE PROVIDED

I contacted Old Mutual on the 01-Sep 2020 requesting a cancellation on one of my policies. Firstly i spent a whole hour being transferred from Pillar to post, i was then informed by a rude agent that i need to send a letter requesting cancellation. I drafted a letter and forwarded it to an email address that was provided. A few weeks later i received confirmation that my policy was cancelled but to my surprise i am still being debited for a policy that i had cancelled in September! I have tried numerous times to contact old mutual and im still being transferred from Pillar to Post its actually so frustrating!!!
