Not responding to my emails

I have been paying a Momentum Funeral Cover for the past 6 years, without any claim. As I was browsing through their website, I discovered that clients get one year's cash after 5 years. I sent them 2 emails already, without response, to find out why have I not received any cash back. I find it pathetic that you are quick to call us when you need us to join but now its an effort to give me information that i'm entitled to. I'm tempted to cancel this policy &amp
