police ignoring my emails

hi, I'm trying to report a groomer(m28) that groomed me when I was at the age of 6-7 I'm 17 now and I can't move on from it ever I already confronted his girlfriend and his girlfriend defended him and blocked me and now the new south wales police isn't responding to me what should I do? I'm scared he wiped out all photos he has of me already but I have evidence of him showing guilt
