Unable to get assistance from Discovery

I signed up to Vitality a year ago. Since then, I changed banks. I have been trying for months to change my bank account for Vitality, so that the premium is deducted from my new bank account, without success.

Calling their call centre is a waste of time and airtime. You will spend more than 5 minutes selecting options and verifying your identity etc etc, then when you are about to be transferred to an agent to explain your issue, the call disconnects. Then you have to go through the whole process again.

At one stage I managed to get hold of an agent, who sent me a form to complete (DHRCBD002). The form mentions nothing about Vitality banking details.

This is my last hope to actually get someone from Discovery to contact me and assist with this issue.
