Insurance Funeral Plan to be canceled

I am struggling with Old Mutual Insurance, regarding a policy that I have not approved with them, Funeral plan. They have been debiting my account since October 2024, I have been corresponding with them since March on email, to cancel this plan and to return my Funds as I am unemployed. I have received a call last week from them in regards to the plan, and I told them that I canceled it since March and no correspondence has been inactive. I have completed documents as requested from them and still no reply. I am sick and tired of these insurances just doing what they want and when it comes by doing the right procedures to refund it takes 3months and still nothing. Regards Noleen Slinger
