Discover is going out of their way to be unhelpful

I have been a member of Discovery Health since July 2013. Due to living abroad & not being a member of a SA medical aid for at least 3 months prior, myself & my daughter was excluded from chronic care & medication for our heart conditions for a full year which meant our visits to the cardiologists and medication had to be paid out of our pockets. After a year we were approved for chronic care & medication and was still left out of pocket as the visits only included cover up to R2,300 and even the chronic medication are not covered in full. We are relocating abroad early February. I am currently paying over R5,000 per month & as termination has to be done per calendar month, I had no choice to have my membership terminated only at the end of February & have to pay for a full month. I have requested an additional month's supply of my chronic medication seeing that I am paying for February too. I have been denied an additional months supply as they say if I collect my medication next week, I will have a supply for February. I feel I am being left out of pocket again as I am denied medication for a month I a paying for & they are laughing all the way to the bank. This to me is unfair.
