Old Mutual group scheme is robbing poor clients and refusing to pay at the policy maturity.

I was paying towards my Old Mutual group scheme policy for 32 years and I took early retirement in 2010 and Old Mutual declared the policy fully paid up. I was advised to claim for all the benefits in this policy when I turn 65. In December 2023 I turned 65 but Old Mutual could not trace this policy. After I wrote the email to Jurie Strydom the CE for Old Mutual the policy was found and they say it was cancelled with no communication written to me. What makes things worse there is an amount of R14000 paid to a FNB account which I dont have. I have been pleading with Old Mutual to pay me back all the prmiums that I paid for over 30 years with interest but they are refusing.
