Discovery Insure changes policy without notifying client

Our electricity went off for almost 28 hours. All our food for Christmas that was in the freezer spoilt. According to my policy schedule. Discovery covers food spoilage. I logged a claim on the 23/12. Had no feedback from the claims consultant. So I called today. And was told by Busi that my claim has been declined due to the nature of the electrical outage. We had to now spend another 4000 rand to purchase more food for the household. Furthermore discovery makes these changes to our policies and we were not notified. No email, sms or message on the app. We are loyal clients of Discovery Health, bank and insure and yet their customer service is not up to scratch. I don’t trust discovery insure and what benefits they claim to offer anymore. It’s seems like they don’t care about their customers
