Dotsure Pet Medical Aid

I signed my dog up to Dotsure Medical Aid. I opted for the Basic Plan originally. I had fantastic service from Mazibulo Myo. I then decided I would like to upgrade to the Superior Plan specifically for the Hereditary conditions. I was told that I cannot claim on this plan for 12 months for any hereditary condition that might arise eg Hip Dysplasia etc. How ridiculous is this? I understand there is a waiting period but 12 months?? So Dotsure is happy to take my R430 but I cannot claim for any hereditary condition that might arise in the next 12 months? What is is the use of being on the Superior Plan then? I have cancelled my membership with Dotsure. I am extremely disappointed as I have always heard so much about Dotsure. Clearly there are many snags. Listen carefully to the Ts&Cs before joining.
