Forget trying to put in a hospital claim

It is impossible to contact iWYZE or get them to contact you if you want to register a hospital claim. I am fed up. I have been trying for a week, and according to their past documentation, my time frame has expired. They make it so difficult to register a claim compared to other companies that I think people give up. Payment goes off promptly, but service is non-existent. I am changing insurance today. Thousands of rands wasted over the years on nothing.
