0 after sale service

I've been awaiting feedback from VA Durbanville for months now. It'll soon be a year since I took out my membership and I'm still having issues. They activated my membership incorrectly, after I provided the correct details and now it's affecting my Vitality. They're clearly only interested in writing new business and does not care for after sale service. I was promised that the issue would be resolved and that feedback would be provided. No one has contacted me since late Nov last year and I have no idea what has been done since.
