Trying to add my partner to my health plan but no help from Discovery

I wanted to add my partner to my health plan.

The first customer services person I spoke to on the phone put me on hold for over 5 minutes and never called me back. After I gave a bad rating a lady called to then apologise and said she would organise an agent to call me within two days. That was over a week ago!

Discovery - do you no longer want my custom after almost 15 years and do you also not want the new business from my partner??
