Call centre pathetic

The call centre ***is pathetic. This year I had so many issues with claims etc not being paid and everytime it takes multiple calls and weeks before it gets sorted. My condition is approved for PMB. Yesterday the pharmacy contacted me and said Discovery won't pay.. after its been working okay for a few months. Just got off another 20min call with Discovery and all the call agent can tell me is that its been escalated to the PMB department and that it will take 2 to 3 days to get sorted. No worry in the world that I'm sitting here and needing my medication today... FED UP of fighting and empty promises
