Extremely poor medical aid call centre setup

I've been trying three times today contacting the contact centre on *** regarding a recent claim. I've spent a totol of almost 25 minutes on the line just to get throught to a consultant. The latest attempt from my side - they hang up in my ear just before the consultant could establish contact. Nobody from the call centre attempted to contact me back. I've been with this medical aid since May 2009 and this is the service that I'm getting from them. I'm so frustrated by the poor setup of the Discovery medical aid contact centre. Definitely a zero rating from my side. Calvin van Wyk
