Getsavvi mammogram

I am extremely disappointed in these guys services. They broadcasting all over the internet and their webiste about their benefits yet when I tried to find out re my benefit for a mammogram I was it's not covered. Womens health is part of preventitive screening which clearly shows on their site but the consultant seemed surprised when I did the query. Is this a way to mislead clients to take out their insurance and why will it not be covered when they have a whole article on their site about screening and prevention benefits.
