Vitality Call Centre Agents - Completely Unsure

I've just spent 20 minutes on the phone with Discovery Vitality Call Centre transferred from pillar to post without any assistance, I cannot fathom how speaking to 5 different agents could still not resolve my problem. I have had an issue with the Vitality Active Rewards on the Discovery app for months now and I get the same feedback asking to send a screenshot which I have done many times and still this hasn't changed. I am actually at my wits end my query has been escalated before and still it was not resolved, how can there be no consistency with resolutions? Its as if departments to do not actively communicate with one another. WHAT ELSE DO I NEED TO DO TO GET THIS RESOLVED? STAND ON MY HEAD!!!<br>
