1life body shaming

I want to share my dissatisfaction with 1life. they claim not to be discriminating against anyone including people with HIV. I took a life cover with 1 life in February 2021 and I was told to go for medicals so that they can get my hiv status and I did my tests came out negative and with excitement I thought there it is I finally have life cover to secure something for my son but today on the 12th of may they tell me that they will not cover me because of my weight, so is it ok to discriminate against a person's built? I am not sick, I don't have any chronics and its not even in my family but they decided my son doesn't deserve to have a better life once I'm gone because I'm fat. Im active, I work I love life and I didn't choose to be built the way I am. 1 life is trying to body shame me and I want to put it out there.
