Horrible and thieving company

This horrible company offered to insure my mother’s life, harassed her to take life insurance of which she has been paying her premiums each and every month. She recently passed away and the insurance is saying she had a chronic illness which she had when she took this cover,

Why would you insure a person that Chronic when you say you do not cover them and take premiums on a monthly that is ********** and misleading to say the least. This is a crime and will be taking it to a legal firm
