Beware of Medihelp/Medihell

I am a newish member of Medihelp, less than 12 months. I was booked for a small procedure but once trying to obtain authorization I was was declined as I did not disclose I had a different but similar ailment 7 years prior. I was with held my operation that could become life threatening and told it would be reviewed by the "non disclosure committee". I am referring their premiums to the "non premium commitee" now. I am sure there are other medical aids around.
