Bad Service

I am currently with Discovery and want to switch to my wife's medical aid, which is also with Discovery. we filled in the Application forms but due to a misunderstanding it was not emailed for the change to take effect as of 1 March - I already submitted my cancellation from 1 March as well. Now discovery refuses to start covering from 1 March saying that I can only start from 1 April, as I am moving to my wife's classic saver plan, and I have to reinstate my previous discovery Membership, to cancel it again 27 days later, or being without medical aid in the interim. Great loyalty after being with Discovery for 10 years. just illustrates again, that you cannot expect anything from big corporates.
