Poor admin and lack of ownership from Metropolitan Funeral management and admin tean

On 12 August 2021 we took out a Metropolitan funeral plan. On 14 August 2021 when I received the contract I rep**** with a copy ID and indicated that one of the beneficiaries date of birth was captured incorrectly. This beneficiary is also disabled and will be a child for life, which I sent supportding documents for. On requesting the changes again the younger brother who is normal able bodied, was made the child for life and the date of birth for the disabled young man was still not rectified. The premium is or has been incorrect since inception. It is almost billing again and the issue has now in 5 months not been corrected. How difficult is the admin of changing a date of birth? Should there be a claim, I dont want an issues with admin in an emotional state to get the staff trained on how to correct client's detail. I am deeply saddened by the lack of ownership of management of Metrop;itan on the error made by Metropolitan admin staff. We all will die and do need a funeral plan. Metroplitan is making the thought of a members death even more daunting due to the lack of their ability to capture client details correctly,
