Appalling first time experience, I even want to cancel.

I am fuming with anger right now. the sense of no care form their call centre is appalling. So I took this cover for my dad and they spoke very well and sounded very professional during the registration process.Two months have passed and two debit orders have gone through. In our very first experience of using this cover, on monday 03 June my dad went to 3 different dentists in their list of designated providers and all three refused to help him saying this medical aid doesn't pay/settle claims. I called their customer care line yesterday and spoke to Busisiwe who promised to refer my query to the escalation department and would get back to me on the same day. I got no call back. I just called them back now and Lerato told me that these queries take 3 working days to resolve irrespective of the patient's state or level of sickness. She told me all patients' queries are urgent so mine can't be prioritised. I'm beyond angry. This is not what I expected when I took this cover.
