Impossible to talk to a human at the call centre!

I read in one of the old newsletters that members can get up to R800 per member per year contribution from Discovery towards a heart rate monitor. I am simply trying to find out how I go about using that benefit. I cannot find any answers on the web site. Last week I tried to call Discovery but held for close to 30 minutes due to call volumes!! I tried to call again now and was again advised that my minimum hold time will be 15 minutes. Who has this kind of time to waste? Discovery I have always been so impressed with your call centre in the past. Right now you are failing miserably in this department!! I have been trying to talk to a human being for days with still no luck. Please could you urgently get someone to call me or email me on how I can utilise the R800 contribution towards a new heart rate monitor. Do I simply buy the device and send through the invoice? Or is there a process that needs to be followed? And please don't make excuses that your call centre is extra busy because your Vitality promotions are so successful. Staff up or don't run promotions you can't handle!!
