Access to login nedgroup medical scheme

I've been trying since forever to try and retrieve my username and password , to login onto the site with no success. I've sent emails and no one responds. All I want is a medical aid certificate that I need to use asap but it seems its a mountain to climb to get this damn certificate. Poor service I must say, it is always a hassle to contact nedgroup or Medscheme, coming from bankmed , I must say , the are extremely below par when it comes to customer service. I think I should go back to Discovery this is pathetic.
