Frustrated

I haven't gotten any claims in over 4 months. I have no idea what's the reason. I don't receive any points when my referrals join. Am I doing something wrong? I do have one tasks that I thought would fall off from about 4 months ago. It was a pedigree claim that unfortunately went out of stock so I couldn't complete the task. Could that be the reason I am not receiving any claims? I check the app everyday. I answer questions and try to stay engaged but nothing.
