Metropolitan : DOA

I signed up for a Metropolitan Family Funeral policy on 26/07/2007 for myself, my wife and three sons. The original policy includes all 5 members of my family, but the latest update only include my wife and myself. In emails sent on the 28 April, 25 August,, and on numerous phone calls, etc. I have been regularly requesting for my children to be included on the policy as originally stated. The Emails, holding on direct line phone calls for 20 minutes, nothing seems to awaken anything but an electronic response. I am in my 70's, Co-vid is rampant, I would like the assurance that this issue is clearly sorted before I or any of my family need to claim.
