Despicably absent customer service - they can't be bothered to respond to multiple lines of contact

I took the time to do the health assessment, completed it, got the results on my phone. No problem. However, when i received the formal notifications, the information differed from what i received (it no longer had me classified as having a medical aid; my fitness level went from good to fair). I went on-line, there were 2 separate results for the same evaluation, again with errors. The main point of this rant is that it is IMPOSSIBLE to get anyone there to contact you to feedback what has gone wrong. I have : Phoned twice and spoken to 2 separate agents; I've done the on-line chat with an agent (who kept me for nearly 30 minutes, only to tell me that it is being 'escalated')., i've sent e-mails, I've even responded to an email 'survey' that they sent out. No response from anyone, 10 days later. This is despicable service to a paying customer.
