Momentum- Notice of Death and the black void of silence by this company to clients

I submitted a notice of Death I February 2025 also executor yet the devision working with settlements don't have any way of being comtacted on other than email - They dont respond or acknowledge documents received - They dont provide feedback on the process status They basically write policies and totally ignore after sales of these policies . I have received much better service from smaller insurance companies than Momentum - I would like the devision responsible for death payouts to get in contact so we as a family can understand what is the actual dead silence pun intensded on financial matters!
