will not do any business with Old Mutual again - Worst service ever

I've been trying for over a year to cancel an insurance. Every day, I call in and speak with a different consultant, and even if I provide a reference number, I have to explain myself several times. This is absurd. In January 2022, I paid off my Nedbank Home loan , which included a cession with an old mutual. I then went to the Old Mutual Kenilworth Centre branch and requested a cancellation of my life policy as it was paid up, but the policy was not cancelled because I needed to give a no cession letter, which Nedbank had issued to Old Mutual, and I had sent it through, but there has been no proof that the policy has been cancelled. You are not treating me fairly as a client; my policy is current, all I want is for my policy to be cancelled and refunded because the Nedbank was already paid up in January 2022. If another Debit order is deducted, I will contact the Ombudsman. I will not do business with or suggest OLD MUTUAL to anyone because it has become impossible to assist with such a simple activity.
