Chronic condition - with no support from Fedhdalth!!

I thought prevention was better (and WAY more cheaper) than cure! Not if you are with Fedhealth. Despite having had COPD for many years and having the condition 'in my basket' my doctor contacted them to motivate my daily use of Duolin, which prevents the COPD from progressing. It is very expensive (R340.00) a month - but as usual Fedhealth turned down the doctor's request. Does not make sense to me, as I will no doubt be having to visit my pulmanologist again and spend yet another two weeks in hospital. All so very avoidable - and at huge cost to Fedhealth. Can someone please explain your reasoning here - cause to anyone's mind prevention IS better than cure - and so much more cheaper. Please put my Duolin on chronic - I need it to continue to live a healthy life. You don't treat your pensiners very fairly - we've been with Fedhealth for 25+++ years - during all our 'healthy years' and now we are treated so poorly in our golden years.
