No follow up by Discovery Health

I have been trying for the last week or so,to get details of an upgrade to my existing health cover, but whilst the web site is extensive, I wish to talk to a consultant to clear up a number of items. On two different occasions was told some one would phone me ,and on both occasions ,this has not happened. As this change must occur in December, I hoped it would be to Discovery and my benefit to give me the information I need, so that the change could be made timeously.. I hope it is not another example of not walking the talk.
