Its hard to understand but I have a bad relationship with my dad and his parents. I wsn't aloud to refer to them and grandpaents just by there name. My dad left me when I was 3. I know my grandparents address and number but I write and ring and never get a reply they have 3 randchildren now and a son in law and I am scared they have gone before getting to see them. I don't know what to do.
