Pointless, mindless bureaucracy

I have been trying to "upgrade" to Discovery's credit card for days now. The irony of how impossible and inefficient and user unfriendly process I have been trying to follow is laughable; in fact if I didn't laugh at Discovery's arrogance in giving me this run around, I would cry. I have had a platinum Discovery Card for years, which was managed by FirstRand in the past. But it is a stipulation to switch to the Bank if one wants to qualify for the Apple Watch vitality benefit, which is my primary goal. The reason why I can't upgrade I am told, is that my cellphone number is listed as my secondary not primary number. Not only has Discovery card been using this number for years, but this is there mix up not mine. When I went onto their website, there are no instructions to follow as to how to do it & the call centre insisted that I do it myself. This is old style bureaucracy at its most inefficient, pointless worst.
