Unhappy

I opened a policy on behalf of my father and was told he’d have to complete medical underwriting for the policy to be valid but no one has contact neither me nor me for this , this will lead to us having issues come claim stage , I’ve sent emails and received a response one after which I was never contacted again , at this point I just want to cancel and get the premiums I’ve paid back because that’s being ****** . They know very well the cover is redundant without the underwriting .
