Waiting period done but not yet effective

I have taken a funeral policy with Hollard. Unfortunately one of my family member died of cancer. I then went to claim knowing that the waiting period is 6 months that's what I was told when I first tool the policy it's only when I went to claim that no actually the waiting period is 9 months . My mother died on the 3rd of April and I joined Hollard on the 1st of July so that's exactly 9 months but when I went to them I was told no actually it's 8 months. Please can you help me
