Discovery Customer Service non exiting

I am currently a member of Discovery Health, i have been trying for the last two weeks to add 1 adult dependent and one child, and also to change my plan effective 01 January 2019. My partner is now 54 years old, he was on my medical from 2004 - 2012 and again on my Discovery medical from 2013 -2016. I was sent a letter for a 50% late joiner fee apparently because he wasn't on medical aid from the age of 35 - 40 and then again not on medical aid for the last two years. After sending proof of previous medical aid membership - late joiner penalty was said to be changed to 25% . I am still waiting for the new letter with this on to arrive. The excuse is that they are waiting for the 2019 rates to pull through, strange as the new rates are already available on the internet to view. Seems Discovery has enough clients and customer service have really gone down tremendously. Maybe looking at other medical aids is a better option, i might even get a reply from them.

PS - thank you Discovery for my automatic reply received to my email, stating that my request will be processed soon ..... that was last week
