Liberty accepts policy, then comes back with condi

I app**** for life insurance, dreaded disease and disability cover with Liberty. When my broker came to see me, I declared that I had a minor, very common heart condition. They obtained reports from my cardiologist, and shortly after I was told that my policy had been accepted without any special conditions/exclusions. <br> <br> 1 week after accepting my policy, I received a call from my broker- He explained that Liberty is no longer accepting the policy and has made a counter offer.<br> <br> THIS IS ABSOLUTELY RIDICULOUS, IF NOT *******! How can an insurance company just change the conditions when they see fit. <br> When I claim for an illness, are they just going to send an update excluding that?<br> <br> <br>
