I requested Old Mutual to change my registration number last August 22, 2024, but it was only completed yesterday (September 2, 2025) after I followed up on the matter. I did not receive any explanation as to why the change was not made when initially requested. Additionally, I expressed my dissatisfaction with the significant increase in my premium and requested a call with them, but have not received a response regarding that matter. Instead, I received an updated document with only the change of registration number and no acknowledgement of my other requests. This lack of follow-up and communication reflects poor customer service.
