Refuse to pay for chronic medication!!!

I am diabetic and I'm insulin dependent. I obtain my insulin from Dischem, previously Discovery would pay 80% and I would pay the balance.<br> However now its the other way around as Discovery have decided that Dischem is no longer the preferred supplier.<br> As to be expected from discovery they never bothered to inform me of this.<br> I lodged a complaint on their web site but as usual with discovery nobody has bothered to call me.<br> <br> Discovery are super quick to take my money every month but refuse to pay for anything, whats the point of a medical aid then???
