Today I logged a claim which one of the people insured by my late mother passed on last week on the 27 .07.2022 with the policy number GT***X3 which they said both in from branch and head office that the policy lapsed in June 2022. They have not informed anyone . They said I was not informed because I was not the beneficiary , the beneficiary is my late mother ,she passed on,on the 27 March 2022. The last payment was received on the 04 . 03 2022. I was not informed because I am not the benefiary ,I asked at the branch if I can pay the 3month difference they said it is not done like that it lapsed. Question how am I gonna know if the policy lapsed because now the person needs to be buried .I think Avbob failed the deceased here.
