Call Centre Waiting is Totally Unacceptable

I am trying to speak to someone at the call centre and have been attempting to do so since last week. I understand members qualify for a R800 contribution towards heart rate monitors. I am trying to find out how to utilise this contribution. When I phoned last week I was left holding for nearly half an hour!!! I tried again this morning and was told by the electronic voice that my waiting time would be a minimum of 15 minutes. Who has that sort of time to waste?! Apparently your call centre is experiencing high volumes due to your successful Vitality promotions. If you can't handle all the calls, staff up or don't run promotions you can't handle. Do I merely buy the device and send the invoice through? Is there a specific process to follow? I cannot find the answer to this question on your web site. Please can someone call me or email me so I can get some answers.
