Disappointed in rare Discovery incompetence

I needed to make changes to a Discovery Wellness Centre Sandton appointment. The website directed me to your call centre number *** (groan). I called to ask for the number. The call centre agent provided me with the number *** which I recognised (having used it a month ago) as being one where a prerecorded voice message tells you bookings can (must?) now be made directly with the relevant centre, and the numbers are provided one by one. I told the agent this and requested the direct number for Sandton Wellness Centre which she was unable to provide. Come on DIscovery! Update your systems! All numbers should be easily available on your website! If you cant do that, then make sure your call centres have ALL the relevant numbers. I should not have to make 3 phone calls when I could make only 1! You are wasting my time and money, and making work for your call centres! Or is that perhaps the point so you can boast about the 36400 calls your call centres handle daily? I am so disappointed in my favourite SA company....
